I play PC games, because...Tradition, the fact that the open ended nature of the system means it is a more natural platform for unusual, innovative indie games and mods, I find mouse and keyboard exponentially better then a controller for over 99% of games (And practically the only option for some whole genres), I need a computer anyways so its cheaper in the long run (And steam deals save me even more money), and I love digital distribution. Also, I'm tech savvy enough that the hiccups in tech arn't a big deal, and am not overly bothered by ports.
