For starters the online gaming community on PC is much, much more polite, friendly and intelligent than your average xbox live lobby (there are a few exceptions admittedly). When I hopped over to playing games on pc I was amazed when people weren't; a)having a massive fight, b)falling for trolls,and c) spamming the chat with dick jokes.
as much as i want to agree with this, this isn't true. if you play the recent games like BO2 or BF3 you get the kiddies, the hackusations and the retards and when you play older games you get the "lol kanker feggit" very noob unfriendly people. i actually enjoy that older community, but it isn't for everyone.
it's still multiplayer games, there is a reason why shoutcasters have the chat disabled at events
