Well, Osu isn't mainstream, yet it still has a community with about 89% to 93% idiots (based on the people I have seen post here, at the very least). That's quite a lot, even without being mainstream. :pB1rd wrote:
Smaller communities are always better, being mainstream tends to attract a lot of idiots.
In this case I can't really agree with you, because if the community is already below average (depending on your point of view, that is), more players can only equal a rise in quality. It's actually pretty logical math-wise:
If the number is <0 (in this case, 0 is the sum of all the players adding up to be right in the middle - average), adding a bunch of randomly generated numbers (people being either mongrelic and utterly idiotic, or brilliant), it's always going to slowly go back to 0, unless there is a bias pushing it to generate lower numbers (but that wouldn't be RNG anymore).
Likewise, if the quality was above 0, adding a bunch of random numbers would slowly bring it down.
Regardless, you should look forward to meeting new people, and you might just meet someone who you particularly like and share common ideas with. Having the same community time and time again would result in it getting stale and eventually dying out, and you want improvement, right?
