I don't know if anyone said this before. 10 pages is a lot to read. If these points are duplicate, just consider this support to the original.
1. Touhou danmaku thrive by having good and meaningful patterns. So, it would be good to separate the standard mode from touhosu. That means, no generation from standard to touhosu.
2. In-game editor may be too much to handle. Every bullet have to be placed manually? Hardly possible. In-game editor provides some basic patterns? That would take away the beauty of variety of danmaku. So, I am thinking of using scripts. For general idea, something like these:
a. danmakufu-like script (those videos on the first 2 pages are from danmakufu, and
they have their own script to generate patterns.)
b. Javascript interpreter and a library to support it. (Like
what Adobe does with ExtendScript)
c. Lua interpreter and a library.
d. Any other programming/scripting language that is appropriate. (aka you get the point)
3. As most Touhou original songs (i.e. with artist ZUN) are already ranked, I think when submitting, we should be able to "add difficulty to existing map". I know this requires changes to be made in the database, but hey, it isn't that bad. :/
Well, apart from the suggestions, here is my opinion.
I AM A TOUHOUNERD. (just saying)
1. If there were a Touhosu! mode, I can foresee myself going crazy making danmaku. So "no one's gonna make it" is invalid argument.
2. Touhosu! will be even more "irrelevant" to the rhythm game genre (e.g. when compared to CTB). If there were Touhosu, soon there will be osu!craft where you fight zombies and mine according to music(i.e. not rhythm game anymore), and finally My Little Posu!ny, where MLP episodes will be made into MAD according to music(i.e. not game anymore). I support the idea of Touhosu!, but still, this is something to consider.
3. Even more people with crazy skill will pop up from nowhere. (we have Cookiezi for standard, Remilia-Scarlet for mania, not sure about CTB and taiko, never checked)
4. Touhou with DT/HD/FL will be fun!
