I've played crysis2 all the away through in 3D and it's epic! Absolutely fantastic game! The huds hang out of the screen and you feel integrated with the suit in the game.
Also played uncharted 3, batman AC, mortal kombat and it does make a nice change than playing in 2D.
The only drawback I have with it is I cannot play for anything longer than an hour in 3D mode without getting fatigued (yet watching avatar in 3d for over 2 hours is fine!) so it definitely gives me a sensory overload.
