Best and worst gaming community?

In my opinion one of the best communities is the Team Fortress 2 community. Most players are real nice and friendly even to noobies. Plus most of them are fun to play with and create such nonsense such as: link

And the worst? The Blizzard and Call of Duty community. The latter is composed of crazy elitists who will gang up on tu and think you're a worthless human being for not being a good player o if tu are a new player. The former is composed of immature brats and people who only care about their KDR than winning the game.
