You want a real answer? None. Every single franchise has a sperg running it because it's these kinds of people that have the time and the patience to run these games, for better or worse. That being said, really niche games tend to have only one or two people really dedicated to it, which lowers your odds of finding someone unpleasant.
Personally, the best communities I've seen were FF Type-0 and Pokémon Colosseum . They are also the smallest.
