the one at the local walmart has been frozen the 3 times i have been in there. was froze on Resistance fall of man, unless there is another FPS out for the console.
The PS3 at my local gamestop froze while I was playing Motorstorm as well. Of course, I've seen the 360 kiosk freeze up there as well. I own an Xbox, a GameCube, and an Xbox 360 and none of them have ever frozen on any game, so I feel fortunate.
