If there was some sort of online rpg (not MMOs...games like phantasy star online, monster hunter, etc.), that would most likely have one of the best/most chill community. After that would be random arcade type games (stuff like castle crashers, castlevania harmony of despair, and bomberman live for example). Other then those type of games I really couldn't tell ya.
Like someone else has said, there is no such thing as no hate/trolls and all that fun stuff. I personally always had the best luck with online rpg type games (met a good bit of friends back in 2001 on dreamcast PSO...I still play with some of them to this day).

to me, virtua fighter 5 final showdown when it was new and active. castlevania harmony of despairs online is good to, but thats only cause its you and people online fighting the computer instead of eachother. which is cool as hell.
