I just play games on PC because it's easier and more comfortable for me personally. I like using kb/m for games. I like options. Things like that.
I don't really relate to the average PC person because I don't play RTS games, MMO games stink, tower defense is agony, uh, I don't have a facebook account. I mainly play the same types of games I play on consoles, like shooters, rpgs, action, adventure and all those good genres. But I do really like eurojank games like STALKER that are as ambitious as they are busted.
I have nothing against consoles, though. Games are just better on PC for me. If I was into that community thing, then yeah, I'd totally be about the Xbox. If I was into home folding not the Xbox 360, I'd be into the PS3. If I was into...ok, I probably wouldn't be into the Wii regardless. I don't expect others to share values. I don't really rage hard about Crysis 2, or Dragon Age 2, or contarding or anything like that, at least not seriously with that level of fervor. It's generalizing, but hardcore PC peoples can be nutty about that stuff.
