Same here.
Other reasons I play on Xbox...it`s relaxing playing from the couch, on huge plasma TV with sound through decent 5.1 Logitech speakers. The Xbox controller is perfect for the game. It looks gorgeous on my big TV through the console, oh and no CTD`s unlike when I played it on my new Quad Core system.
Hmmm... why would I play on console

No need to explain. Too many PC gamers think that consoles are somehow "unworthy". I know. I used to be one of them, but at the end of the day... it's simpler, it's less hassle, and it tends to just work. If you're time poor, and just want to fire up a game for an hour or so of fun, consoles are IT! Whilst sometimes I think of making another gaming machine, and linking it to a 360 controller, I have to think to myself... is it worth it? Sure, you can get mods on a lot of games, but when you break it down to $$$ spent per game... oy, it usually works out to be a lot of money.
Nothing against PC gamers - go nuts boys, but in general, the whole "I play on PC so I am teh bettrs is just stoopid.
Oh, and my 67" TV says "hello baby" when I walk in the door.
