Xbox 360 for me! After having my PS2 fuck up numerous times, I went to orignal Xbox, which worked fine. So when it came time to go to the next level, I stuck with Xbox.
Also, not a big fan of Playstation's controler.
(Also I have one of those lucky 360's that doesn't overheat!)
(Also, although the Wii looks interesting after trying a friends, I really don't like the motion controls - the damn thing never does what I want it to do, and I can't picture myself laying on the couch waving my arms around like a beached whale.:1orglaugh)
