I have recently played a lot of Chivalry: Medieval Warfare on PC, and I was kind of blown away by how ****ty so many people are. The game is fun, and I adapted and became equally ****ty, but it's like everyone is just miserable playing that game. Lots of whining, accusations, etc. There are 4 player classes, and it seems like everyone has a gripe about each class. You just can't win, someone is getting butthurt. Recently, I started a multiplayer sessions by typing "GET READY TO EAT A D*** SANDWICH MUTH ****AS". I paused and thought, "Wow, I just typed that." That game brought out the worst in me.
Most of my other gaming experience was with Left 4 Dead 2, which on the elite levels (Realism: Expert) has a pretty solid community. There is an occasional troll, but I have quite a few Steam friends through that game and we will coordinate games. I haven't made a single friend on Chivalry and don't want any association with those bastards whatsoever.
So, what do you think are the best and worst gaming communities? I listed the two above examples because they're recent, but I'd have to say:
1) BEST. The old Star Wars Galaxies MMO. I had so many great times playing this game.
2) Chivalry is close, but Call of Duty was pretty garbage. I played about 4 hours before I had enough. Never returned.
