I was going to say 360, but looking at its game catalog... but right now its games just don't interest me. The only title that does is Banjo-Threeie... and well, that's not out yet.
So I guess I would go PC, with the definitive versions of Bioshock and The Orange Box (I'm not a huge fan of shooters, but these titles are great, and I love Team Fortress 2). I'll no doubt be playing some quirky custom map on WarCraft III as well. Eat your heart out WinterMaul!
