Bulletstorm all the way, hands down, no contest, hell yes! BulletStorm offers some over the top violence in ways I've NEVER seen in a video game before. Even when compared to Duke Nukem! In BulletStorm you can shoot your enemies in the butt and get credit for that, you can shoot 'em in the nuts and get credit for that....if you shoot 'em in the throat, you get different points than their head. You got some pretty awesome weapons, u got bullet time on the sniper rifle, you get extra points if you shoot someone while you're drunk! the environmental kills can be awesome too, impaling someone on a wall is fun....splattering blood is so much fun!
Crysis 2 is not as much fun as the first one if you haven't played the first one, its better, so I would just get it on the PC or something...
From what I know on Portal 2, if you have CFW PS3, you can't play it b/c its using the ENCRYPTED 3.60 keys on that one..
