Unfortunately, what's fun for many hardcore mania people may not be fun for everyone that loves mania. Yes, I love mania... and I love autoconverts. That doesn't make me a "pp farmer" and that doesn't make me "not a true mania fan". Frankly, I find it a little disheartening about how many so-called "real" mania players think that anyone who enjoys autoconverts are only farming "bad maps" for pp and should just "get on the bandwagon and play "real" maps instead".

In reality, I know I'm not as pro as the top players... and I know that the mania specific maps are much more challenging to play. But, I also don't expect to have the same pp as the top players and I understand that most autoconverts should be worth less, because they aren't at the same skill level as many mania specific maps.

I do, however, still want to participate in the fun of being ranked, without being forced to play the mania specific maps, which currently I don't find very enjoyable, because my brain can't keep up with the patterns. So long as the easier autoconverts are worth less pp than the more challenging mania specific maps, I don't see the problem with them factoring in to the overall ranking.

It's not like I'm not making an effort when playing the autoconverts - to me they are both fun and challenging, but to say that because all this time, effort, and real enjoyment were spent on "bad" maps that it's somehow worthless and not in the spirit of the game makes me sad. I don't find most autoconverts bad (yes, some of the old ones are badly timed, but I suspect the standard maps they were converted from were badly timed as well).

Anyway, take what you will from this - I just wanted to share some feelings from "the other side" of mania, because I feel I also have a valid view point, seeing as how much I love mania mode above all the others.

They are kinda bad though. I get what you're saying like you don't want to be forced to play maps that are too hard for you, and I agree. You should try some of the easier mania spec maps. Not only are they much more fun but they will also help you improve faster. The only problem is that atm we don't have much true beginner mania spec maps atm. Well, actually it's more that we just don't have many ranked mania spec maps at all.

I still see one problem in it. For example, I'm not really concerned about all these anime-based or nightcore maps, because I'm simply not into it. I prefer electronic music, rock music and something like that. And then, when I want to be ranked (because I do want), I'm forced to play maps I simply hate listening to, which often results in a worse performance.

I'm playing mostly for fun, with no urgent chase for a high ranking place, but from these 80 osumania maps, as someone has already said, there might be... 10 or so that are not based on asian themes. What then? Do I have to play 10 same maps over and over to go higher in score? Please take in account that not every player is a proffesional mania! player and won't play every song which is given, but still wants to be ranked.

to me to be of
more notes per second hardest
whether either 4k or 7k but if that consideration is more difficult to play 7k

The experience you've got by playing autoconverts is not 100% wasted. It's more like you, just like I did, and pretty much everyone who didn't play any mania games till o!m did, just need a bit of time to get used to mania-spec maps. I don't know, I might sound like an elitist or something, but playing a game which is not meant to be played this way feels wrong in my eyes. I myself "wasted" 6 months of my playtime playing auticonverts, but I got to know the joy of mania-spec maps by myself. I was starting to feel like autoconverts were just plain boring and they featured all the same gameplay. It's a bit sad to say it this way, but people who got stuck into playing autoconverts are simply victims of the birth of a new game mode which hadn't any maps at first (and tbh they were not really promoted as well. Only those who kept an eye on the game mode knew of their existence until a few months ago).

By making newcomers play mania-spec maps, the mode will go towards the right direction. Letting them get lost in the autoconverts would be a big mistake from our side, who knows o!m for a good amount of time already.

Sorry if I sounded harsh, I didn't mean to harm anyone by voicing my opinion.

Also take note that I'm trying my hardest to change things now since we probably won't see another chance coming up until god knows when.

putting aside the issue of the state of mania
this is a discussion about competitive ranking
if you can't play mania maps as good as somebody else - then you don't deserve the same rank as them
as simple as that.
which is why autoconverts shouldn't weight as much. if you can play mania maps just as good, then you have no problem getting your points from actual mania maps. if all you can play are autoconvert and can't play mania maps, then you don't deserve the same rank to begin with. players shouldn't be forced to farm autoconverts to catch up to less good players who simply farm more

if for some reason you enjoy playing those autoconverts nobody stops you from playing them; but then play them just for that and not for a rank on a competitive ranking board

The issue is, there are literally no maps, which are available for begginers to play. Even those with one or one and a half star are seemingly as hard as four-star auto-converts. I don't want to sound offensive, but there is no worse way of encouraging new people to play osu!mania than slapping them in the face with way too difficult songs. And they won't have an indicator of their progress when they will play (therefore unranked) auto-converts so they won't know whether they can start playind mania!specs or not. The process of introducing new ranking system needs to be long, and the first part of it has to be making loads of new maps, especially easier ones, if you want osu!mania to go this way.

Just noticed: I realised that you speak like every mania!spec map was perfectly timed and super-accurate. I don't really know hat makes them look like that, but the process of choosing a mania!spec map to be ranked is similar to the case of standard maps, and, as you see, there are maps which are worse, and that's what bad auto-converts come from.

no
if you don't like the songs already ranked then map some up and try to get them ranked.

having autoconverts contribute to ranking only further encourages people to not bother mapping mania songs, which then in turn makes it so people don't want to remove them from PP because there's not enough songs without them. The sooner they're removed the sooner we might see more people playing/making mania-specific maps

it's not like removing them from ranking removes the maps entirely. People can still play them, they can still practice on them, and they can still enjoy them. They just won't become within the top 100 rank by playing them all day long.

I appreciate your opinion I just haven't reached this point yet I suppose and still find the autoconverts more fun to play than the mania specific maps, which I either fail three seconds into or spend the whole time feeling like I'm playing "catch up" with the notes and patterns and miss the song. I play because I like to feel in the music, but with most mania specific maps being too complex for me (the 7k ones anyway - because I like those the best ), I end up spending too much time feeling like "how can I get my fingers to conform to this pattern" instead of enjoying the song.

Maybe it's like Xcrypt said... there's not enough beginner mania specific maps. If there were more at my level, maybe I wouldn't feel this way.

Autoconverts need to be counted (for now), because we only have like 80 mania maps (with only a small handful of them being non-7K, screwing over most players) lol.

I don't see the problem with using them anyway: mania-specific maps have more objects/density, and typically have higher OD, so they'll be much more rewarding. PPv2 cannot be farmed like PP, so only your best scores (legit maps) will matter. Nobody needs to worry about autoconverts.

Edit: TL;DR: mania maps will naturally be worth more anyway

There's still way too few mania maps to completely ignore autoconverts.
I'm completely for the idea of knocking out autoconverts, even though I play a lot of them, but that's maybe something to consider when there's enough maps to not have 300 people stuck on the same pp because they SS everything.

As for keys, why not do as ppv1 did and just take into consideration the score penalty from the key mods? You don't need to penalise the pp itself. I've yet to see a map where playing it in 4K makes it any harder than it originally is. 8K doesn't mean it's going to be easier either, so 0.95 or so might be just enough.
That's for the autoconverts though.
Maybe when they get SR working properly we could find something for mania maps, but as they stand at the moment, why not just keep it as it was in ppv1?

Why even make a new pp system

Just a side note for those of you who think there aren't enough beginner maps, or think that o!m is simply too hard.

t/146615

In this thread, there also is a link to Entozer's Map List in which you can find many maps ranging from pure beginner to super pro. Sure, most of them are unranked/unsubmitted, but I do confirm that beginners maps exist. It just takes some effort to find them. I'm getting off topic here though.

I don't understand. If auto-converts are so dull and provide all the same gameplay, why don't even the best auto-converts (which are more accurate than some mania!specs, by the way) have only 1-million-scores on their rank charts? They are so predictable that everyone can max them easily, can't they? Let's take the example of... I don't know, a Talent Shredder. Noone maxed it yet, and, as you keep saying, it uses such a recognisable pattern, that it should be millioned, shouldn't it? You cannot say that this map is badly converted, because you might as well call some mania!spec maps bad.

I'd like to mention a few things considering how I plan on tackling this.

The general direction:

1. First of all, everyone can decide on his/her own which maps he deems good or bad, or which ones he/she prefers playing. We shouldn't be forcing certain maps on people by making them worth more for no sensible reason.
2. I'll try to make an algorithm that's fair for both auto-converts and mode-specific maps. We will all see how it turns out, and if it's alright, then I see no reason to reduce the value of auto-converts. As mentioned above you are still free to play the maps you prefer playing. I can however understand where the auto-convert argument is coming from, and it'll definitely be addressed if there won't be a good solution that weights all maps the same.
3. Default X-key modes exist for each specific beatmap for a reason. My initial plan is to give slightly more points to the default X-key mode of a particular beatmap than any custom one. This is not set in stone yet and most likely will change in one way or another while testing.
4. Unfortunately X-key specific ranking is not going to happen. That'd be for one part a way too huge amount of things to manage and for the other would clutter up everything.

Beatmap difficulty:

This is were you all can help the most. My current concept is somewhere along the following: Similarly to how tp works with osu! standard maps I would like to instroduce strain values to measure how hard it is to play a certain map. This essentially means, that a higher note density will also be considered harder, while the algorithm is aware, that using a single hand or finger multiple times in a row is more demanding than simply alternating.
For mods the map will simply be transformed accordingly to what standard does in the moment. HR will increase OD, DT the speed at which the map plays back, etc.
I have not yet gone in-depth and it would be great if you could give me hints of what the hardest patterns are and how to rate difficulty. Any X-key feedback is welcome!

@Janio : Adding more random notes to make harder chordstreams and whatnot is not changing the gameplay. Autoconverts are bad in the way they are... "mapped" :that is, there is no logic in how the notes are falling in anyway. There is a difference between a stupidly hard map without any sense and an extreme but well mapped map.

Tom94 wrote:

technically there's no such thing as harder "patterns" (due to shape etc), although pretty much everybody would agree that ring/middle trills are a problem to play (which is also why shields are hard) - at least in the beginning - but this is easily neglected by players playing better and doesn't weight enough to make a big impact (as in, trills are just about as hard with all other fingers too)

in the end it's all density (where 1 LN = 2 density) and jacks/finger usage repeat in short timeframes.

also stuff like 8 1/4 notes is harder than 4 chords of 2 notes, so 'amount of timing snap divisions peaks' might also be a "thing".

You can look into the thread I linked earlier (my side note post). There is pattern repository which can give you an idea of what's hard and what's not.

Please do not make HR change AR. AR is something that is really depedant on players. Some play better with lower, some with higher. I like it how it works now (everyone can choose their scrolling speed). Also I really appreciate your attempt! awesome
If you need like any specific help, feel free to message me. Like I don't feel like actually coding myself atm but I wouldn't mind helping out here and there on the actual algorithm. I'm not a great mathematician nor programmer nor player, but I do have a some understanding of how they work.

these last arguments I've seen make me glad I'm not involved in this

"everybody is wrong except me" - everyone

autoconverts were not made for mania, that's a fact, autoconverts don't play like real mania maps- especially on higher levels, that's a fact too. as a matter of fact they play like shit and shouldn't ever be used as an example of mania done right but you're free to enjoy your shit and roll in it as much as you want

map compelxity is not given only by density, that's a fact too (e.g. so called 'gay' patterns)

if you'd say the devil is in the details a tiered system for charts has been the way the insane bms scale does it and it works. o2pf does this as well, and guess what. it works.

calling a shitty autogenerated chart better than charts that have been thought from scratch (and in detail) is honestly insulting to all the communities that came before osu!mania like it's the grand savior of vertical scrolling rhythm games

guess what: it isn't. thousands of shitty autogenerated charts that enjoyable are miles away from the real deal, and it's easy to see that a lot of people here have been spoiled (which I feared from day one)

but hey, I'm some sort of troll in everyone else's eyes so disregard me

I don't know what I was thinking when I wrote my post. Of course, HR will not change AR in mania, my bad. Must have been with one of the other modes in my head.

Your opinion is not disregarded. However it's not the purpose of a ranking system to guide the players towards what they want to play. It is merely there for rating performance, and that depends solely on how hard a map is, not on how subjectively well-made it is.
Of course "hardness" already is a very subjective thing, but let's not overcomplicate it by adding more factors. As I said, if a general system won't work, then another solution will have to be found.

Tom94 wrote:

So mods are going to come in and affect your pp?

For your difficulity judging: An algorithm is nice and all, but I think there is also a alternate possibility of letting experienced players determine how hard that map is before it becomes ranked. That would probably be quite accurate (sort of like the level system in o2, except better because o2 has a lot of 'wrong' levels on maps.)
Also Agka I think you are right but I also think you are a troll haha. Maybe you can share how the insane scale BMS or o2pf system works?

Alright, after seeing that side of it, I'm gonna have to go ahead and join your side.

At first I thought autoconverts shouldn't be counted. They're pretty meh compared to actual mania-spec songs. I do play a good amount of converts though, but only because I like the song. I'm not really big on how they're converted. It irks me. Because of that, I wouldn't mind if they weren't ranked, but I didn't think about the other side. I forgot what it was like to be in that position. When I started off, I couldn't even touch mania-spec songs. They are challenging and the patterns can be off-putting. I wanted to have fun, not fail instantly.

I'm going to go ahead and say that autoconverts should be counted in rankings for now. Make them worth much less than mania-spec songs, but still include them. At least until we have a sizable amount of songs that less-skilled players can have fun with. If we kick out autoconverts, we are kicking a large amount of people from the rankings. That doesn't sound very fair. Just because they can't pass or don't enjoy the mania-spec songs because of their difficulty, doesn't mean they shouldn't be allowed to be ranked.

The problem is that autoconverts actively hurt the mode and its community. They give people a wrong idea and mislead new players in multiple ways.

1. The keymode of autoconverts goes up with difficulty, what makes people think that you can "work up" from 4K to 7K, while that's not the case. You could be playing 4K for years and still be unable to play 7K at all. You're supposed to learn 7K (or maybe even 8K) as soon as possible, after you can play it you can manage all lower keymodes with just a few plays. We have a lot of players who started with 4K and never moved up because they got comfortable with their 4K skill, while they'd have to start over to learn 7K.
2. They often have nothing to do with music. That makes people think it's what the mode is about, while real mania is about playing the music, not playing along with the music.
3. They don't feature patterns. You could get great at mania but as soon as you see something like brackets or complex LNs you're clueless in real mania. Autoconverts don't even feature something as simple as one LN starting at the same time another one ends.
4. They distract players from the fact we don't have a lot of maps. Unranking autoconverts would make people notice that and in addition to more real mania players we'd also get more mappers.

Just to clarify... I'm in no way calling autoconvert maps "better constructed" than mania specific maps. Yes, I realize that a lot of work goes into making actual mania specific maps, which I'm sure are great for people at that level. The problem that I ran into was whenever I tried to play even the "easy" 1 star mania specific maps was that they were too complex for my skill level. I'd compare them to "difficult normal" or "easy hard" autoconvert maps.

I don't know about most people, but I couldn't make the jump straight into mania specific maps due to their complexity, which left me feeling discouraged from either constantly failing the supposedly "easy" maps, or barely keeping up with them, which killed my enjoyment of the song. This is why to me autoconverts were always more enjoyable.

Should people be locked out of the ranking because they aren't that advanced yet? I would hope not... All I want is for people to be ranked in accordance to what they can play - where naturally most autoconverts would have less of a difficulty rating, which would translate into a fair amount of pp.

Anyway, I hope no one took what I said as an insult to the mapping community - you all do fabulous work I'm sure, but I'm not skilled enough yet to be able to enjoy it very much.

As a side note, this discussion has prompted me to give mania specific maps another try and I'm pleased to report that I'm now able to complete the "easy" maps. Though I don't find them very easy at all lol...

Just the map, not pp i guess?...
And Tom also mentioned that HR will not change AR in mania previously.

https://osu.ppy.sh/forum/t/147552

This may be of some help regarding difficulty.

IMO there are 3 main areas of difficulty in osu!m:
1. Note Density (As stated previously by many others) - Both density of notes for burst sections and overall NPS (Notes per Second) should be one of the main areas to judge difficulty
2. Holds/Long Notes - Holds have their own set of difficulty and really test finger independence. While it may not be as dense key-count-wise as a burst of dense notes it adds its own complexity via hammerheads, inverted holds, etc (More in Drace's thread that was posted earlier https://osu.ppy.sh/forum/t/146615).
3. Speed Value(SV) Changes - Some files may not be as dense nor as complex hold-wise, but can trip people up with SV changes. This requires a lot of adaption with reading skills and can be really difficult at times.

Uhh... Does autoconvert counts with the pp for mania? If not i kinda disagree.. Many players rely on autoconverted maps as they could just score better than the usual mania map. If the autoconvert does not count in the pp then i assumr you really need to upgrade the community for mania. Modder/BATs etc. Because with such lack of people who are doing mania maps how can we rank if autoconvert doesnt count as the pp. Either way if you can only gain pp in a mania map only. I think it will be very hard fot some people that doesnt start to play mania yet. And thus the pp will work very slow if you cannot gain pp on autoconverted maps.

Addition: we really need to work up on judgement rate for mania

but yes, what are you doing in competitions if you can't even do the basic stuff? Do you really go to a robotics competition without knowing how to build your own robot and expect to compete with your basic electronics knowledge? Or do you try to compare what you know with doctors when you only have high-school level biology?

o2pf works a bit like this.

There's different skill levels- High class, Demon, Monster, Lost Humanity (off the top of my head)

To move from one skill level to the next you complete a set of challenges and move onto it. Some of the challenges include being able to one-on-one someone of that skill level and beat him/her, as well as the basic "pass this map under certain requirements" or so.

You could easily adopt something similar while accounting to the different dimensions of skill that mania play offers.

Overall, accuracy, LN, etc..

Forgive me if I'm wrong, but I thought ranked competitions were made to rank ALL players according to their skill. If I'm the worst mania player in existence, then give me the very lowest rank. That way I'll know where I stand and can celebrate small increases in rank as I become a better player.

To say lesser skilled people are not even worthy of being ranked isn't in the spirit of competition, from my point of view anyway.

Just a few comments from someone relatively new to mania (my ranking used to be around 880).

I agree with all the previous comments saying that auto-converts should be weighed a LOT less than mania specific maps. No matter how hard the song is in osu mode (lets say FOUR DIMENSIONS Freedom Dive, or 0108 Scarlet Rose, or even Madness Precipitation for 狂気ちんでん), auto-converts never reach surpass a certain level of difficulty. Unlike most MX or SHD maps (or even HD maps), auto-converts never include (from my experience, not necessarily accurate, sorry if I'm using personal terminology, I'll try my best to be clear, I might be editing this list):

1. Holding long notes before the previous long note is finished (nearly every HD+ map includes holding long notes halfway into another long note, or letting go of one long note before the other one is finished, if you really need an example, fripSide - future gazer http://osu.ppy.sh/s/115715)
2. "Burst" maps, even though not necessarily a good determinant of skill, but still a good reference (i.e: KOTOKO - unfinished http://osu.ppy.sh/s/102519)
3. Melodic sweeps (I'm not saying the occasional 5 note sweep, I mean shit like MEPHISTO MX) and sweeping holds (bj. Halo - Ende SHD http://osu.ppy.sh/s/79132, or MEPHISTO SHD)
4. Actual beatmaps, not rhythmmaps (Silent Siren - Stella http://osu.ppy.sh/s/81166)

I'm perfectly aware that 4k can definitely get as hard as 7k, but I also believe that 7k should be the standard for mania (or else why would the system be limited to hitting a maximum of 6 notes simultaneously). Anything out of 7k should be left just for recreation purposes, and should be weighed less in comparison to 7k. Accuracy shouldn't be weighed as heavily as in other modes, as it would just encourage people to play auto-convert and easy maps. You could consider counting the MAX to 300 ratio, as I think that would be a rather accurate way of determining one's skill. You're making a brilliant move in tallying all scores (not only the top 50), as all mode-specific maps are a hell lot harder to go into top 50. All mods should be left the way they are right now.

I'll try to add to this whenever I have time, quite busy right now.

To say lesser skilled people are not even worthy of being ranked isn't in the spirit of competition, from my point of view anyway.

I'm fine with this, but then why would you weigh autoconverts the same skilled people play?

that's the point

I'm sorry you've misunderstood me. I've always been stating that since autoconverts aren't as challenging as the mania specific maps that they should be weighted accordingly for pp.

Here's my previously posted thoughts on the subject so you don't have to do searching...

yeah, as I said as long as autoconverts are weighted very, very low, almost negligible (as I harshly said before)

Please, autoconverts should NOT be included in the ranking formula.

I'm sure this was said, but autoconverts really kill the rankings. It's a little bs seeing myself being beaten by ranked 20k people and then I beat a rank 20 something.

EDIT: Or rank autoconverts difficulty accordingly to the mania star difficulty. For example, people are complaining that a 5 star autoconvert is as hard as a one-two star o!m specific map. When changing into mania mode, they should adjust the star difficulty accordingly, this way they'll have less weighting.

I think that autoconverts should be ranked too, but as stated before, they should be lowly weighted to the ranking system. Since you should play mania-spec maps to get a better rank I think that also would be a good motivation for some players that actually want to be good at the game and not just have a high rank

Letting ACs be ranked at all (no matter how much they weight, 0 is only proper value) should make hitsounding and correct timing of objects the ONLY ranking criteria for osu!mania, I see no logical reason why a bot can make something superbad that is accountable and a human can't. So either remove them from new rankings or change o!mania demands for chart being rankable.

first of all, i'm sorry my english to sucks (trying to makes everyone understand of this post)

maybe is it just me or i don't wanna seeing pp system ?

why i rejecting pp system ? the reason is simple : farmer player will try gaining pp as he / she can, and the result, rank owns anything right ? (from outside view)

and the idea of only gaining pp by playing mania-specific-beatmap is still not good, if you cant play hardest diff, just try the easiest diff, get SS, and get so many pp, done.

and i'm not gonna say anything about auto-convert beatmaps, since some auto-convert beatmaps for me is fun (maybe just for listening song ?), and when i arrive to this game we're only get a very few mania-specific-beatmaps (and because of that, pro + ET players tend to play a lot of unranked, pending beatmaps)

+ the idea of mods gaining more score is kinda terrible too... i'm not good almost at all mods and the acc in this game really damn hard (especially if you try FC / Perfect in 1 beatmap, but the pattern makes it kinda impossible to do, and now we're getting some mods = ++ score ? hahaha hell no dude...)

and sorry i know this maybe a little bit OOT, but what i'm trying to suggest is only this :
- trying to find new system ranking (some players find a ranking makes the game competitive right ? but old pp system kinda makes me lost there...)
- and the most of all, try lighten a bit of osu!mania mapping ranking rules, so in the future this mode have a lot of mania-specific-beatmap, lots of osumania players, and the most of it, mappers are enjoy to create them, and targeting to makes his / her beatmap to ranked...

that's all i got to complain and suggesting...

but autoconverts are so wrong it's like playing scatman on standard vs these new maps

I completely suck at mania and at this point can pass all the autoconverts in existence. (Some are hard to play though, extreme fantasy etc)
If you're having trouble passing autoconverts then... -_-

There's already 80 ranked mania mapsets, with usually 3-4 diffs per one. That's already plenty, and with the increased amount of mania BATs the ranking speed of new mania charts has drastically gone up. Autoconverts are no longer needed.

Completely judging a map set on your own skills doesn't determine the actual difficulty for the general mania players. Someone's version of 'sucking' at a game can be considered as somewhat advanced in another's eyes.
I agree that mania maps are harder, yes... but just rank them properly in accordance to the real difficulty. Why is it so hard just to increase the stars they were given? There is no right in taking out autoconverts completely. Some may prefer the 'fun' maps that have been made for the osu!standard mode.
As for the original keys set for osu mania (such as sdf etc) people change the keys to how they prefer to play. Some may play better with the original keys set, while others prefer a custom key set. Decreasing a score based on what key sets people use allows no common sense in this matter.
Also, calling players who play the osu!standard converted maps 'not real mania players' is utter and complete bs. Play 0108 converted maps and tell me if that's 'too easy'.
Ganbatte on the new system tom. Hope everything works out well for the ranking system in development.

in my opinion

why not big 500 got a few pp such 1-10 pp(1-2 for easy,3-5 normal,5-7 hard and 7-10 for insane)

but 1st place got a bonus pp 20 and big 50 got bonus 10 pp and big 100 got 3 pp


it should be easy for make an opinion like this :3

but i'm afraid if it will make people confuse XD

Unless I'm mistaken, people weren't talking about the actual keys uses to play the game, but rather the key mods. Like if the map is originally 7 key, but someone plays it using the 4 key mod, the score would be decreased.

I was replying to Tom's idea.

Forgot to mention that anyone who thinks the converted maps are all 'easy' should go SS all the hard's and insanes.

Pearl Phoenix wrote:

They are not easy actually, they are quite hard, but for the wrong reasons

Also, please we should stop worrying about autoconverts for now. If there's a system that applies weights to the difficulity of the maps, autoconverts become worthless for everyone except new players. Help Tom with what he needs help with instead, that is determining the difficulty of the maps, and it's not that easy to do.

If this is to be done right, the auto-converts shouldn't be ranked at all.

First of all, those autoconverts wouldn't pass the ranking process if they were submitted like mania maps. Many maps gots notes mapped to stuff that mania maps normally wouldn't. The long note's release are not correctly timed. And no matter the map, you'll never have something layering multiple tracks which is pretty much the essence of multi key games like this. These maps were converted from a 1k source and the patterns processed by a semi-controlled randomization.

With autoconverts, speed is the ONLY difficulty factor. You will never find difficult patterns. "Difficult patterns" are patterns that would still be difficult when slowed down because of how the notes are placed. I would agree to a certain extent with the people that mentioned that the people that play autoconverts exclusively aren't true mania players. The whole difficulty ladder in all similar rhythm games is learning and recognizing different patterns after extended play, even the standard mode. But the maps converted from there are stripped from the clever patterns they once had and become a useless junk with single-dimension difficulty.

Imagine converting a mania map to standard, and having circles timed with the notes (or chords) with randomized placement, yeah. Someone who never played standard would think "what's wrong with that?". But I'm pretty sure every standard player who read that just cringed. That's how it is for mania ACs.

There is no reason at all these should be ranked. They can be there for a larger song library, but there is no sense in having stuff that doesn't accurately determine a player's skill play part in the ranking system. We got mania maps for that and that's all we need.

To everyone who doesn't understand what I'm saying look at this. http://osu.ppy.sh/forum/t/146615 and scroll down to the pattern repository. Now try and find autos that feature anything but beginner patterns. All those "omg so hard" autos are just fast beginner and maybe novice level patterns. Keep in mind that this is a just a fraction of "common" patterns. Harder maps all feature unique stuff to make them memorable.

(I apologize for the the self-promotion, but I honestly don't know of a better repository.)

----------------------------------------------------------------------------------------------------------------------

Enough saying what already known, I'm gonna introduce a couple other points here.

People are saying that maybe there isn't enough mania maps to run the ranking system. Well truth is there's more than enough. There is currently more ranked mania than any DJmax games, any IIDX machine, (I'm assuming that goes for DDR too), than any Rock Band or Guitar Hero games (excluding DLC) and mania's playerbase is smaller than any of those games. Having those 30'000+ (diffs) ranked autos was waaaaay too much anyways. People with no skill could accumulate PP by going no life and playing every single one of them.

And we could also think about the mappers, what motivation can they have to make maps when the majority of players are playing autos? Their map will just get lost and unappreciated. And what about modding? The playerbase playing autos have a bunch of songs to play and the idea of helping getting more maps ranked doesn't even cross their minds. I'm pretty sure unranking the autos will not only motivate mappers to try and rank more maps, but also spark interest within the mania playerbase to help as well. A well needed kick start.

I personally believe unranking the autos is the best possible move, lets forget those atrocities ever happened and start fresh.

-- About PPv2
It's nice and all that ppv2 gives huge priority to mania maps, but honestly it's still useless if easy/normal are still giving more pp than hard/insane simply because there's more ranked plays.

What if the pp system weighed the songs the total unique players ranked on all difficulties, and then weighing that again per diff on the mapset?

Regarding the big auto-convert discussion:
I'm fairly positive, that a good difficulty algorithm would rate auto-converts extremely low, because they (mostly) are so easy compared to mania charts, so you would naturally have them worth less, not artificially by excluding them. Keep in mind, that the ranking system is meant to work for everyone, even the people who just start with mania who can't just dive into the mania-specific maps, or want a big map diversity at their lower level of skill.

The current system does not look at how many ranked plays there are or anything. It is not done calculating yet, so please don't judge it yet. And even when it's done a way more precise version will follow in a few weeks when the difficulty algorithm is implemented. You will be able to give feedback on beatmap weightings earlier than that; I'll be posting some lists and your feedback will decide what to take.

I can't help but wonder, will pp still be delivered accordingly to how many other players who has actually played a certain map. Will there be any reward in passing the high difficulty osumania specific maps that has a low success rate?

Any answer is appreciated. Thanks.

Edit: I really appreciate the time and effort you're putting into this Tom.

Just to clarify, by unranking I don't mean removing their ranking boards, I mean making them not count towards PP.

If you're new to the point that the easiest mania map is too hard for you, what good would a rank be anyways? Do you want to shove the fact that they aren't good in their face by displaying that 2mil+rank?

And It's completely impossible to make an accurate algorithm for difficulties, it's best to limit the pool of possibilities to what we know is good material instead of depending on an algorithm to tell it for us. AKA only mania-specific maps.

As far as I know, ppv2 for mania will function like osu!tp - where your best scores determine your rank, making it impossible to farm at a higher level. If anything, this will encourage people to play the more difficult mania maps instead of ac.

Also, thanks for your work Tom

That way you get the same points with 3 top 500 and with a top 1. I think higher scores should be rewarded much better.

That said, I think that only mania-specific maps should be ranked.

This is how plan on doing it. Only your score and the map are relevant for your score - other players and their scores are not. Doing statistical analysis on 2 different maps usually is not working well, because not the same players play the same maps.

For judging difficulty, I'd say we should do this right and introduce a new BAT-like group of expert players to give maps a starcount of a custom difficulty scale. I personally know a fair amount of active ETs that would gladly volunteer.

Though of course this would never work if the autos still count for PP.......................

Then who is supposed to manage that team, choose who is suited and confirm, that decisions are correct? While with a lot of work it might be possible, an automated system is the only possibility, since there is a huge lack of manpower. After it working very well in standard I see no reason to not at least try it osu!mania, too.

I think there would be many players willing to join this team. It would be the easiest (Playing charts before they're about to be ranked and assigning difficulties) and wouldn't take as much time. There are many players who have the capability so assign difficulties.

About the people managing and choosing who is suited and confirm, I believe the first couple of people should volunteer and then be voted on by the community. After that, the team can accept new members.

We've seen how biased community votes can be in the top-players votings. It's more of a popularity thing than a capability thing. Before pushing in that direction I'd like to give an automatic difficulty system my best, though. If it ends up working, then it saves an incredible amount of time and work - and there would be no need for funky multipliers on autoconverts and such.

I disagree, mania has the potential of having a much larger playerbase than standard itself due to people migrating from other similar games. Only problem being most leave because of "this and that". The manpower is there, and the one in charge should be designated by someone who already has authority, or by the community.

"Working very well in standard", quite the ambiguous statement.

What I'm worried about is the higher level maps, I'm sorry but i seriously doubt anyone but a couple BATs can actually tell the difference in difficulty in maps higher then lets say o2jam lv40 or so, maybe even lower. Mania also has many more dimensions to it's difficulty (I'm not calling it harder) than standard, a density check with a couple common pattern recognition can lead to be greatly deceiving.

Like I said before, I know a great deal of trust worthy high level players that would gladly help. Mania doesn't have to follow in the footsteps of standard.

For a starters... there isn't even 100k solid players playing mania. Secondly, ranks inspire people to improve. Surely people would understand that that would be how it starts out for every new player. Each converted map and mania specific has it's own special difficulty.

I can't disagree with anything you said, but I still see no reason to not at least try the difficulty approach. I can assure you, that I don't plan to do just simple density checks. The people you mention who can tell the difference between difficulty of maps will surely be able to help me fine-tune such an algorithm to see whether it could be working.

Yes that's true about the voters being biased, I'm not sure on how to combat that.

About the automatic difficulty system, it will be very hard to appropriately put a difficulty on songs. I can complete some 11 star songs, but I can't even finish some 2-3 star maps because the patterns are so foreign to me (basic ln walls). Note density and speed are factors in a difficulty, but I think the pattern is what defines how difficult a map is, which makes it very hard for an automated program. This is why I think a team dedicated to judging the difficulty of songs is the best option, and no matter what, a real players judgement will trump almost any program
Edit: typos

At least let him try... Don't be negative about this attempt just because you've never seen it done well before. I don't expect it to be super accurate but I think it can be accurate enough to at least give the rankings some meaning. And while I think letting expert players determine the diffs of the mapsets is also a viable way to go, it also has its flaws.

Tom94 did a miracle with std pp, I feel safe trusting him to do mania pp too.

Alright let me try something (if I may)

Here's some maps where the current star system grades too low, meaning their much harder than they let on if you look at their star count.

https://osu.ppy.sh/s/133891
https://osu.ppy.sh/s/131228
https://osu.ppy.sh/s/92012

And here's some maps that are overrated.

https://osu.ppy.sh/b/235027&m=3 (lv 18)
https://osu.ppy.sh/s/104030 (lv21)
https://osu.ppy.sh/b/284854&m=3 (lv36) lololol
(I'm claiming this based on the performance I see of certain play vs their performance on lower star counts)


Seems the biggest (not only) problem with the current system is not giving enough points toward long notes and brackets, and too much points towards density

I don't really think it's fair to completely invalidate auto-converts. From what I can tell, osu! does a pretty bang up job on converting. But excluding that, the ranking system isn't meant to judge what songs are "valid" or not, that's what a song being approved/ranked does.

The ranking system is designed to determine the skill level of a player comparable to his/her fellow players. It simply wouldn't make since for a kick ass player to have all of their time thrown down the drain from playing auto-converts and have a rank far worse than some elitist that only plays !mania maps, but can only play at about the same skill level as a baboon sitting on the keyboard!

Scale them slightly? Sure, I can understand that. Invalidate them entirely? Perish the thought, it's asinine and rather unfair.

Kick ass players who score very high scores on ACs usually plays mania-spec maps as well. Don't confuse elitist players with players who play the game mode how it is supposed to be played.

There are 1001 reasons for which we should totally eliminate them from the mania ranking system. Every counter-arguments I've read so far are half-assed.

The points every "pro-mania-spec players" wanted to show are all grouped into Drace's post (page 6).

Please don't talk about autoconverts vs. mania-spec maps if you don't know anything about the game-mode.

Good luck with the ranking system, Tom.

I'm thinking of something about determining maps' density. I might throw this idea into the Feature Requests sometime later : what about a toggle (similar to how Kiai is applied currently - from a point of time to another) to be applied on a certain part of the song which would eliminate this part from the density count ? That is, several songs have some calm parts which don't have many notes at the said part, and as such don't reflect the real density of the map. This would also fix the Star Rating to a certain extent. I believe this would facilitate your work with the algorithms and all. This would require some work from woc2006 but it shouldn't be too hard to implement.

Thoughts guys ?

Rating auto-converts "extremely low" seems abit drastic to me.
I agree that they shouldn't have the same value as normal osu!mania maps, but I wouldn't want the gap to be massive either.

Dunno if they should be completely ignored (playing the same density for a longer time can be more demanding on your stamina for example), and I don't it's too much of a problem for an algorithm to determine those 'chillax' parts, but this is definitely going in the right direction.

Also another thing I would like to say is you should maybe first try doing some simple pattern checks along with density. Then ask multiple advanced++ players to playtest your system on various maps with different styles and different difficulties. They should be able to pinpoint some of the flaws. Trying to do that all in one go is painful guesswork, imo you will need multiple 'feedback stops' like this.

When I am ready to present some difficulty values I will post them in this thread. As mentioned multiple times I do want to have multiple testing iterations before incorporating the whole thing into a ranking system.

oh ok sorry

Auto converts definitely shouldn't be counted in mania PP. If they are then the PP will mean absolutely nothing. (unless you weight them so low that they are worth nothing in the first place)

There's no such thing as a "kick ass player" who only plays auto-converts, if your skill is anything other than extreme novice you can do any auto-convert in your sleep and would find them extremely boring.

Do people jump in here without reading the past few pages? PPv2 cannot be farmed, and mania maps will be worth a lot more by default - you'll have to play mania maps to get a decent rank. Anyway, this is outside the scope of Tom's work, so this is just clogging up the topic.

Some random thoughts on mania difficulty calc: Would a system similar to TP's aim/speed/acc work? Where 'aim' would be substituted for reading ability or something, which could increase with number of keys, difficult patterns and so on? Obviously not that generalised though.

Speed and accuracy could definitely be a thing. I don't know how you would go and calculate your reading ability, except maybe density you can handle of LN walls vs chord walls? But even so it really depends on the patterns I think.

Why don't you go SS all the hard and insane converts if you think they're so easy then!

Who said he doesn't know anything about the game mode?

Don't get me wrong, I agree the mania maps have a largely increased difficulty to the converted osu!standard maps... but to rule converts out all together is absurd. If there's such a big argument about it, why not just have two smaller ranking systems for mania? One for converts and one for genuine. Would solve the argument being provided here. Just have both ranks running on the same pp algorithm. As a side note, if this is not an option, why not make a poll to see how many people actually want auto converts to not count towards the new ranking system? There are obviously more people playing mania than there are on this forum.

I'm posting this for knowledge sake, as until just recently (24 hours ago or so) I was oblivious to the fact that there was a constant verbal battlefield amongst the forums about "Auto Converts" and "Mania" maps. I've always just played the game picking and choosing songs that peeked my interest song wise, and not difficulty wise. No, I didn't just play the easiest difficulty, but I also didn't beat myself up about not hitting 99%.

So my first question involves the quote below.

Tom94 wrote:

Beatmap difficulty:

This is were you all can help the most. My current concept is somewhere along the following: Similarly to how tp works with osu! standard maps I would like to instroduce strain values to measure how hard it is to play a certain map. This essentially means, that a higher note density will also be considered harder, while the algorithm is aware, that using a single hand or finger multiple times in a row is more demanding than simply alternating.
For mods the map will simply be transformed accordingly to what standard does in the moment. HR will increase OD, DT the speed at which the map plays back, etc.
I have not yet gone in-depth and it would be great if you could give me hints of what the hardest patterns are and how to rate difficulty. Any X-key feedback is welcome!

If this was implemented wouldn't this fix the whole "AC's are garbage and so are the players who play them" argument? It would assess songs and give PP according to their difficulty. Because of this, Mania songs which are made for Mania and thus, harder, would allocate more PP, and AC's that are extremely easy and slow would allocate less. If this is true, it's better than tossing AC's out the side completely due to the fact that you could find a much harder AC song vs a low level Mania song. There may be few among many, but they are there. This couples with the fact that Mania-specific songs do exist, but creating a whole scoring system solely off of the few that are out there (versus Osu! Standard) would limit the amount of songs available to the players (Ranked wise).

I can't stress enough that I've only just started learning about the PP and PPv2 system today, so any or all of this could be complete off base.

people wanting auto-convert maps to be unranked need to get off their high horse. this isnt o2jam, or bms, or djmax. auto-convert maps, whether you like it or not, is a part of osu!mania. they are there for the lack of songs compared to standard and as a means to ease new players into the mode. making them unranked or intentionally penalizing their worth unnecessarily denies a portion of the player base a chance at a ranking.

i would argue that keeping them ranked would encourage more people to play mania-specific maps. if the new ranking system does a good job at defining difficulty, it would notice that auto-convert maps are much easier than mania-specific maps and assign a higher pp value to the mania-specific maps. this means people that only play auto-converted maps will have no chance of getting higher ranks than people that play mania-specific maps. and it would also mean that if the auto-convert player wants to advance higher in the leaderboard, they would eventually have to play mania-specific maps.

in addition to that, auto-converted maps lower the barrier of entry to the leaderboard. it lets new players experience ladder play and see growth without the frustration of endlessly failing a "beginner" mania-specific map. they can learn and get comfortable with the mode on auto-converts, see improvement through their rank (#20,000 -> 19,950 is improvement), and realize that they need to play mania-specific maps when they hit the auto-convert ranking wall.

it also helps deal with the crappy difficulty curve mania-specific maps have. many of the mania-specific map's easy modes are in fact difficult for new players. the mode feels restrictive because current maps do a horrible job at easing in new players. if i tell my sister to play an easy mode song on, say, dj max portable 3 she will most likely pass the song. if i give her an "easy" osu!mania-specific map she will, more often than not, fail spectacularly. it gets even worse when comparing between two difficulties. you can get a good score on say, a normal mania-mode map, but try the next difficulty and the difficulty is 100x harder than the previous. auto-converted songs help deal with the learning cliff when getting into osu!mania which in turn helps people deal with the learning cliff when moving on to higher difficulties.

i honestly do not understand why some people would vote to exclude or penalize a group from something that should be all-inclusive.

Regarding the big auto-convert discussion:
I'm fairly positive, that a good difficulty algorithm would rate auto-converts extremely low, because they (mostly) are so easy compared to mania charts, so you would naturally have them worth less, not artificially by excluding them. Keep in mind, that the ranking system is meant to work for everyone, even the people who just start with mania who can't just dive into the mania-specific maps, or want a big map diversity at their lower level of skill.

so glad you feel this way. reassures me that the system is left in good hands.

and as an unrelated issue, would the difficulty algorithm be able to assign difficulty names? right now, difficulty naming for mania-specific maps is arbitrary, seemingly based on what game the mapper (or song) came from. there are maps with Lv.XX as difficulty in addition to maps with things like HD or MX which really mean nothing unless the player has experience with the source. there should be standardized difficulty names for osu!mania as the arbitrary difficulty names are confusing.

For example:
https://osu.ppy.sh/s/116133
Easy, Normal, Hard, Maximum.
thats good and easy to follow.

https://osu.ppy.sh/s/123456
NOV, ADV, EXH, INF.
i can understand NOV and ADV, but what is EXH and INF? and why is this different than the other map?

https://osu.ppy.sh/s/124866
Beginner Lv.2, NOVICE Lv.6, ADVANCED Lv.8, ADVANCED Lv.12, EXH, EXHAUST Lv.15
i can kind of follow it, but what are the levels for? and why does the second-to-last difficulty not have a level?

https://osu.ppy.sh/s/85585
Level 9, Level 18, Level 36
again, what do the levels mean? is the easiest difficulty for this song harder than all but the 3 hardest difficulties from the previous song?

difficulty names are arbitrary. it should use standard osu names (easy, normal, hard, insane) because this is osu, not o2jam, beatmania, djmax, etc.


and apologies for the wall of text >_>

First of all, to every post against unranking ACs (except Tom, his arguments actually made sense though I don't believe 1 point outclasses the many that's been presented from the other side.). None of you are presenting anything that could even be considered a fragment of a decent argument. Throwing stuff around like it's "absurd", "unfair" and saying we should all "perish the thought" with no basis whatsoever, thinking that it's enough to prove a point. And the slight points raised that could probably make a clueless person nod to the cause are completely overwhelmed and showed to be irrelevant in my previous post. It makes me wounder if anyone bothered reading it. Was it too long? Too hard to understand? Or maybe is it purposely being ignored because there's nothing to be said against it?

If you got nothing productive to say then don't say anything. These posts full of meaningless words are making the thread run around in circles.

Also: there's mania specific songs that first timers can clear. The problem is the the extremely limited 5 star scale that scales o2jam lv1 and o2jam level 9 at the same 1 star making it harder to find them. Saying autoconverts helps people get introduced to the genre is completely superfluous, if needed we can change the ranking criteria for an easier diff, done.

------------------------------------------------------------------------------

As for the difficulty algorithm, I think the pattern repository could be of help for the first couple steps. Also looking at those six maps I posted to find the current system's shortcomings would be great too.

By monitoring single finger density you're covering the jack patterns while single hand isn't necessarily a difficulty indicator. It would depend what patterns are being featured. Changing say a one-handed reverting stairs to a series of brackets will easily double the difficulty without changing the note count or density. Changing said stairs to one handed stairs or some certain form of one handed chord streaming or bursts however will lower the difficulty. And here we got a whole range of difficulties, all on one hand, all the same density. Noticed how I italicized "certain form", some forms of chord streaming or bursts (at the same density) could be considered harder.

At the same density who knows what kind unique easy or hard patterns a mapper could feature, I'm interested in knowing how you plan to handle the "second dimension" of difficulty in mania maps when such cases are possible at any moment of any density.

Let me say upfront that I'm sorry my previous posts about why I support autoconverts apparently didn't even have a fragment of a decent argument. It's not like I wasn't giving my honest and truthful feelings about the mode or not trying my best explain why I feel that 99% of the maps have value (which you'll note I also stated were as a whole less difficult when compared to mania specific maps and should receive comparatively less, but still fairly calculated pp).

In case you missed it, some of my other invalid arguments included my genuinely enjoying the autoconverts and still wanting to participate in the fun of being ranked, without being forced to play the mania specific maps. I also stated that people are actually making an effort when playing the autoconverts (despite all the arguments that they are way too easy/no challenge). I don't find them all easy, in fact, I find many of them to be quite challenging and I'm sure I'm not alone in this. I also touched on how mania specific maps are very limiting in their playability (to me at least) due to their complex patterning and my lack of coordination, so I'm not yet at a point where I find them all that enjoyable.

Also - I mentioned how ranking should be open to everyone, regardless if they choose to play autoconverts or hand crafted maps. So long as the pp system set in place reflects the actual difficulty level for each map, then this shouldn't be a problem. The best players who can actually finish the mania specific maps will be at the top of the board where they belong, but the casual or beginner players who prefer autoconverts or are not yet ready for the difficulty of most mania specific maps can still enjoy being part of the overall rankings.

I hope you find at least a fraction of a "decent" argument in there.

Yes, there are a number of mania maps available, but don't forget, there's only a small portion of that already small selection of mania specific maps that beginners can actually play through. It doesn't offer up much variety. Luckily, there are also autoconverts that first timers can pass. Many, many, more of them in fact. But since they aren't considered to be "real" mania maps, they should be all removed from the pp system. Regardless of if anyone finds them enjoyable or considers them to contain a level of difficulty suited to their playing style. Forget trying to make a pp system that is reflective of their lesser level of difficulty and ranked accordingly - let's just simply not count them anymore, because certain people feel they don't fit their perceived notion about what mania is all about.

But, hey, what do I know? I only love this game more than every other game out there right now and a lot of that love is a direct result of having played the autoconverts which I genuinely do enjoy playing. It's a shame that what I find enjoyable is an abomination and should be eliminated and not allowed to be embraced by those who love it. It's also a shame that anyone who loves this aspect of the game and speaks out to support it is fair game for being insulted and portrayed as having little to no value in the mania community. (This isn't directed at anyone in particular, but just a general observation I've made while reading through the replies in this forum thread.)

And thank you Tom for working on this thankless task for us. I know you will never be able to please everyone, but from you're posts I have no worries as I know you will be trying your best to create a fair pp calculation system inclusive of everyone.

ok. i'll type out my thoughts.

Drace wrote:

First of all, those autoconverts wouldn't pass the ranking process if they were submitted like mania maps. Many maps gots notes mapped to stuff that mania maps normally wouldn't. The long note's release are not correctly timed. And no matter the map, you'll never have something layering multiple tracks which is pretty much the essence of multi key games like this. These maps were converted from a 1k source and the patterns processed by a semi-controlled randomization.

to me, that comes off as "don't rank auto-convert songs because high-level players don't like them." auto-converting standard maps is a major, attractive feature of osu!mania. they don't need to go through the ranking process because they are an inherent feature of osu!mania. whether you like the quality of the maps or not is completely irrelevant. and whether those maps hold up at a high level is also completely irrelevant.

Drace wrote:

With autoconverts, speed is the ONLY difficulty factor. You will never find difficult patterns. "Difficult patterns" are patterns that would still be difficult when slowed down because of how the notes are placed. I would agree to a certain extent with the people that mentioned that the people that play autoconverts exclusively aren't true mania players. The whole difficulty ladder in all similar rhythm games is learning and recognizing different patterns after extended play, even the standard mode. But the maps converted from there are stripped from the clever patterns they once had and become a useless junk with single-dimension difficulty.

you need to recognize that difficulty is relative. speed is extremely difficult for new players. the patterns found in auto-converted maps, while easy to you, are also extremely difficult for new players. instead of seeing this from your current skill level, you need to see it from the perspective of a new player. osu!mania features gameplay requiring skills that are not typically used or trained. having a way for new players to practice the mode using familiar and enjoyable songs while at the same time allowing them a way to participate in ladder play is a great thing.

you also address this point later in your post.

To everyone who doesn't understand what I'm saying look at this. t/146615 and scroll down to the pattern repository. Now try and find autos that feature anything but beginner patterns. All those "omg so hard" autos are just fast beginner and maybe novice level patterns. Keep in mind that this is a just a fraction of "common" patterns. Harder maps all feature unique stuff to make them memorable.

this is the value of auto-convert maps and there is nothing wrong with that. lower difficulties help acclimate a new player to the controls, higher difficulties introduce simple beginner patterns, and the hardest difficulties get the new player used to playing at higher speeds. having them ranked allows a player to track their progress. and when their rank gains start to slow, they should be confident enough to do the easy mania-specific maps.

from what i've been seeing, you are making arguments only from the perspective of a high-level player. you need to also think about the low-level players. the osu!mania ladder should not be some exclusive club open only to the skilled and experienced.

Meh, it has been made clear that ACs are going to be counted anyways. By the way, most mania-spec players who have been posting in here are not all "high-level" players. I would say I am average at best considering the wide range of difficulties mania has to offer. I also don't understand this whole easy mania-spec are too hard. It's true that many mapsets, including unranked ones, have their easier diff being rather hard fir a beginner. But don't make it sound like there is no "real" easy maps for beginners. Heck, I know a bunch a bunch a bunch of people to whom I've introduced mania, and guess what, they kept failing at first like everyone does, and I told them to search for mania-spec maps first. They ended up with mapsets I don't even have and were soon able to clear these "hard-easy" diffs that you guys are complaining about, all within one or two weeks. Nobody said that mania is EZ mode.

So what? you conducted a survey and deduced that only high level players like mania specifics? You're pulling false statements out of fin air in hopes of making a valid argument. What my statement is saying is that the notes do not follow the music, they play along. Notes are randomized and with untimed occurrences. And they're not a "feature" of mania. Mania's feature is simulating playing songs, not tapping random notes to the song's BPM. It's also not a question of difficulty at this point.

Almost everyone I know in mania quit, new players I've introduced and old players I've met. This plague of sub par material was the biggest reason. I've had many new player literally laugh at how what they were playing doesn't match the song. I've offered converts from other songs that only pushed them to move to that game in question. The only people that actually like the auto converts from my own personal experiences are people coming from the standard mode. And I'm sorry, mania isn't standard. If things keep getting compared to it, mania will for ever be nothing mode than a side-mode and it will never flourish.

Yeah, speed is ONLY ONE dimension to a maps difficulty. And easy maps can be found on mania specifics. What are you even trying to prove here?
We're talking about an accurate rating system here. You want this to be a question of who can play fast junk? Even if the difficulty rating rates difficulty accurately, the amount of autos out there outnumbers mania maps to the point that all other dimension's to a map's difficulty will be ignored anyways.

Nothing I said was opinions, it was flat facts about what creates difficulty on map. It was about why autos cannot determine skill accurately. And you're talking about new players as if they'd rather autos over mania-specifics when I seen the exact opposite. Also what's up with this lie about mania specifics being impossible for new players?

aka nothing relevant said

This whole post resolves around the assumption that mania-specifics are hard. When I'm saying a mania map has multiple dimensions to their difficulty, I'm not saying they are harder by default. In fact, because of this multi-dimensional difficulty it's actually much easier to make easier mania specific maps.

New players can still participate in the rankings, there are maps clearable by complete first timers ranked right now and more to come. No the mania song library isn't too small, plus there's much more to come. And for an accurate ranking system, think about this with me.

Auto converts sole difficulty dimensions are speed and density. You won't be seeing tricky patterns, yet there's many fields of tricky patterns a player can specialize in. We got jackhammer pros, long note pros, chord streaming pros, burst pros, layering pros, accuracy pros, survival pros etc etc. And a pro most the time is not a pro in more than 2 or 3 fields. So since autoconvert on got speed and density to decide their difficulty, that means the speed-oriented pros, like chordstreamers and bursters, and accuracy pros, will have the upper hand. There's over 30'000 autoconvert difficulties. Unless autos aren't removed or rendered useless, how are pros specializing in other fields supposed to show their stuff?

If only mania maps count towards PP, every type of pros will have their chance, new players will have their chance, and the overall quality of the song library will be much better. I know what I said was harsh, but the proper counter arguments that should be made here is proving why the game is better off with ranked autos. And the only points I'm seeing about this resolves around stuff about beginner players that is completely wrong.

I was one of these beginners that mania-spec maps supposedly was too hard for. How come I never felt that it was too hard? I worked my way up by almost only playing mania-spec and o2jam converted charts and can now pass MX:s. And that's after half a years practice with one months break every second month (due to school etc.)

There are plenty of mania-spec maps for beginners and they are NOT too hard, both for 4k and 7k players.

Actually me, along with woc and some other people, have osu!mania "TP" project before.

But finally, woc decided to terminate this project (and switch the project into another feasible solution).

What we found is that, using a universal number to calculate for difficulty, is not feasible for osu!mania because people are having too diverse ability, which means the same pattern may be too easy for one player but too hard for another one, vice versa, despite of they having nearly the same skill level. In one word, to accurately calculate the difficulty of the map using only the patterns with one universal numbers is not fair at all, and to sum up multiple numbers doesn't make sense.

TBH our temporary solution include human work (a lot of them), and use player's past performance data other than patterns itself to determine the difficulty.

So far my suggestion is to make this as SIMPLE as possible. It doesn't need to be accurate at all, but being simple is OK. Even star difficulty along with some slight modifier on patterns is OK - because you may find it even harder than osu!tp to keep balance with these patterns.

Interesting. I know that it really depends on what the player spends his time on training, but we also use single diff levels for o2 and BMS right? Same problem there, but I do think the general difficulty is reflected by the level. Also for a ranking system, the difficulty shouldn't be relative to the player, but relative to all players (or one could say objective).

I do still not get why people are debating so much about AC. In my humble opinion, if Tom is doing it right, and i am sure he will, even if the AC will be counted into the ranking, it won't change much because of the simple reasons Drace stated in page 6, even if for the other side. You guys are assuming stuff that has yet to happen. It will not harm anyone, anytime. Letting people that are new to all of this stuff play autoconverts will them provide some sort of nice first steps into the world of mania. It will not hurt the mania community. People being serious about Mania will automatically switch to real Maniadiffs after some time (+ they will see they won't get any pp anymore from AC.)

Please give me one, proper reason why AC shouldnt be included into ranking. They won't do any harm at higher levels. I would understand why they are bad in the old PP system, but the new one will literally crush those trying to get highrank with autoconverts. So where is the real problem?

Just let Tom do his thing before we talk about anything. I bet your worries won't get confirmed in the first place.

Or atleast thats my opinion. If i may be wrong, please tell me.

One reason is that ACs are very different from mania spec maps so it might lead to newer players thinking that the game isn't as fun since more seem to enjoy these mania spec first timer diffs? I do not know if this is true, but if it is it might be something we want to talk about because the instream of new, fresh casual players is quite important for the health of a game, and I feel like the mania scene really needs it atm. Other than that I pretty much agree with what you said.

There are several kind of players, some of which try to play the Maniadiffs right away, and some of which are trying to get into mania playing AC. In my opinion, the only thing to do is to have a FAQ for mania or something in which simple stuff like this is explained, and why AC are not as good as real Maniamaps. But still, its their choice, not ours.

Yeah, FAQ would be good.
I just hope mania mode will grow with a fresh instream of newer players.
The previous game I played, Bloodline Champions, died because of this (or one could said it had just never seen any growth). It was the most fun pvp experience I ever had in my life and I tried a lot of pvp games. But casual players just didn't think the game was fun, they didn't understand the game and they were just cannonfodder once they were matched up with players that sort of knew what they were doing. I think hope is lost for BLC now, but mania can still grow

(About BLC, i never understood how people couldnt understand the game, it really is fun oo) Yes indeed, that is also the one thing i am really concerned about. Mania shall and hopefully will get plenty of new players.

Hmm just wanting to list all the points stated by the "sides" in this thread and the reasoning for these points.
I want this post to be as neutral as possible, and to make it a tl;dr for the entire debate. It'll be easier to see the points brought
up in a single post. If I interpreted some of the points brought up wrong, feel free to tell me and i'll edit it ASAP.

What the debate is about: The judging of the difficulty of beatmaps.

There are two "sides",
1.Eliminating/reducing autoconverts worth to pp and rank, only mania specifics should contribute to rankings. NOT to unrank autos.
2.Letting autoconverts contribute to pp

These are the reasons (that i've heard) to which why players want AC's (autoconverts) to not contribute or barely contribute to pp.

- The quality of AC's
-AC's throws patterns at the player that don't make much sense, and are badly timed. Randomised, untimed patterns.
-The nature of multi-keyed rhythm games is to play multiple sounds at once, AC's only focus on one thing at a time.
-Many other points, but these are the main ones.


-AC's are heavily oriented towards accuracy/speed heavy players.


-Judging skill level is clearer with mania maps.
-Specific maps use patterns specifically tailored for o!m, whereas AC's are just randomly generated.

Here are the reasons in this thread to which why AC's should still count towards rank


- There aren't enough mania specific beatmaps.
-There are 80ish o!m maps, as opposed to 30k+ AC's.
Counter argument from the other side - 80 is enough, and there will be more coming in the future.

- It gives new players a chance to get ranked.
-New players can't even finish the easy o!m difficulties, AC's can at least give them a rank.
Counter argument - Why would new players care about their ranks if they know they're not good enough? They can also earn rank from easy mania specifics, too.

-The mania community has bad standards when it comes to mapping easy difficulties.
-People have started to find AC's more approachable and are more fun, because easy difficulties "suck".


Here is another other point I'd like to bring up
-The use of "slider leniency" in many standard maps aren't just fit for mania.
-The releases for notes are too early, or notes are too late in many AC's.

Let's have an actual proper post on how to measure difficulty.
This exact numerical system is obviously slightly off (a chord of two notes worth more than 2 parallel LNs), but that's a matter of scaling note diff vs LN diff. My goal was not to give an algorithm, but try to explain how mania players read patterns. The lists of base patterns and LN examples obviously aren't exhaustive.
And one other thing, it might be a good idea to count left and right hand strain separately. A section where objects are spread out evenly between all columns is easier than a section with the same amount of objects where they're all played by the same hand (columns 123 / 567).
This post's examples use 7K but most of this should be applicable to other keymodes.
I hope this post will be useful .-.

Also for a ranking system, the difficulty shouldn't be relative to the player, but relative to all players (or one could say objective).

O2 official use nearly the same algorithm as current star difficulty (density based).
And BMS doesn't have an universal difficulty measurement at all!

And yeah, what exactly I was said, is what you have commented: The subjective trap. Which led to the termination of my project.

Answer these simple question, and you will find what subjective trap is.

1. 4K or 7K, which one is harder? (How do you weight 4k/7k?)
2. Maps which is full of hits or maps which is full of holds, which one is harder? (How do you weight holds?)
3. Stairs or random hits, which is harder?
4. What is the definition of "Hard", anyway?

These question actually fires out a war when my project was announced for feedback in Chinese community.

Just take the third as example (which is mentioned in Tear's post).
When osu!mania was on beta, woc ask me this question. I answered random hits, just like what Tear said without any consideration. And this, along with many other feedbacks, are why stairs are so common in ACs "to prevent the map becoming too hard". But after thousands of PC I found myself wrong - I am far better at random hits than stairs. When I discuss this with many players, I found not everyone is like me - some of them is better at stairs, some of them is not. So how do you determine which one is harder? By polling? With a determined factor on this pattern, there would always be some players that benefits most and some players cry out loud, making it unreliable.

And yeah, too many things are just like stairs and random hits. To "balancing" them is pointless.

This is why I say things should be Simple.

We are playing osu!mania for fun, yeah? So why don't we make the calculation fun?
Instead of making tens of patterns having different weight making things hard to understand and isn't reliable at all, why don't we try to point out a way to calculate difficulty easily, like osu!tp, which can be described in 1~2 pages of paper? Actually fairness is not a must, even with TP every one of us have something like "weight" map which is relative easier to just oneself.

1. That's not a big concern of the ranking system. The default mode of a particular map is to be weighted the most. If the amount of hitobjects (and also type, holds and normals that is) stays the same, then they might even be able to get equal treatment.
2. I plan on using per-hand strain values with per-finger strainvalues on top of those. Anyone not familiar with the concept of strain values can check out how tp does it for standard currently. While holds are active other button presses with the same hand give more strain, fingers directly next to the hold even more.
3. I'd say random hits are harder to read while stairs are harder to execute due to the used fingers often being near to each other. But since I'm not a very good mania player that's probably not a very valid opinion.
4. Subjective as fuck, but there is always a way to satisfy most people. If it comes to which maps are the hardest you all pretty much agree, don't you? An algorithm simply needs to find the same maps in about the same order.

These plans don't involve any patterns (yet).

I'm aware, that what I'm proposing might not work out very well (or at all), but as soon as I have something done I'll present you with results. You can then proceed to tell me how good / bad the whole thing is.

Stairs are naturally easier, there's reasoning behind it. If you're worse at stairs, you practiced them much less than everything else.

Yeah I agree xxbidiao, to some extent.
With the example of stairs vs random hits. It really depends on the player, I am mainly a RD user so patterns like stairs are not my best thing.
But if we calculate it according to the average of all players, I think this is the best we can do. Ofcourse, we'll have to guess a bit here and there, but let's say stairs vs random hits, they weigh exactly the same? For example.
Maybe only weigh things that are clearly harder for the majority of the playerbase, like density, LN, jacks etc.

In all honesty this is painful guesswork right now. We'll just have to see at the first release of the new scoring system and then we will be able to pinpoint some flaws I think.

Stairs are easy to execute, but hard to accurately play.
Random hits are easy to accurately play, but hard to execute. (depending on pattern)

At least from my experience.

Yes, exactly. We would have a hard time upon initial release... Maybe on many other issues

And all players average? That doesn't work either, because players of osu!mania is not all the humankind.

Just use 4key vs 7key as example.
We all know that 4key and 7key are difficult to play in different ways. 4K players play 4K insane maps and say 4key is hard; 7K players play 7k insane maps and say 7key is hard. (Please reference to earlier posts on 4key and 7key discussions.)
If you try to average all players, you will most probably get the answer that 7key is harder, because there are more 7key players than 4key ones (Edit: on osu!mania, who can play at least 4k/7k expert maps). But is that the truth?

My point is that don't hope that the ranking system would be 100% accurate (or to say, reliable) - even 10% accurate is nearly impossible to guarantee.
(Edit: Instead of making a complex system that is hard to understand), It would be a good idea to make the algorithm simple and quick enough, even possible to completely substitute star difficulty, regardless of its reliability. Everyone just want to know that 10 star map is harder than 7 star map, doesn't it?
(Actually, woc had considered improvements on star difficulty, but he gave up when finding osu! just lost its response for tens of seconds just calculating every map's SD)

What can I say, I suck at stairs, but they're fun when you can accidentally pass them. I personally get secretly excited and jump with happiness.

Oh, right, on-topic and all: I can't (or shouldn't) complain much since 99,9999% of the maps I played were auto-converts (and hell did they give me pp!) but are there that many mania-specific maps to "cover" all the auto-converted ones? 'Was just wondering that.

how about rank of osu!mania separate become 4 (4k player only,5k,6k and 7k) ?
and every player can only choose 1 or 2 of them
