Controllers are inferior, clumsy shit for all first-person gaming (in fact, driving and fighting games are the only genres which I would say typically demand a controller; mouse/keyboard is equal or superior for just about everything else), and I've never bought that crap about how fabulous it is to be slumped on the couch with a screen in the distance; it was never that great in my console-gaming childhood, I'm not particularly impressed with it at my mate's place with his giant LCD and PS3, and I never pine for it when I'm playing a PC game. In a decade plus of PC gaming, I can count on one hand the games that've been problematic to run*. The console model has flourished not because consoles provide a better gaming experience, but because their games are more troublesome to pirate, and they're idiotproof to set up. The former has nothing to do with me, and, as I'm not an idiot, the latter is irrelevant. Consoles are good for party games, that's about it. Which is fine, don't get me wrong, but... console gaming is crap.
* Unless we include trying to run really old '80s/'90s stuff on a modern rig, but I've usually found a solution in the end -- I daresay I wouldn't be as successful trying to play a Master System cartridge in an X-Box 360...
