That's odd. I seem to perceive the opposite.
I remember forums in World of Warcraft to be full of whine and flaming and almost unusable because of that. But a better example would be APB. I've spent a few hours trying to read the APB forums, but my god... most of it is whine and the rest is flaming and cheat accusations.
I think the crpg community is pretty good compared to others.
TF2 has a much better community than cRPG. If you hit the clan servers, people are a lot nicer, outgoing and supportive on there. The nublet servers are just quiet, cos no one has a mic. And they're morons.
While cRPG doesn't have the worst community ever, it certainly has a few outstanding characters who draw from the dredges of society.
APB is actually worse than this community. APB has cheat accusations flying in real time, and all around morons, idiots, whiners and ragers.
I can't say anything about WoW, I don't play it. But I like the MnB community. You gaise aren't half bad assholes <3
