Mirror's Edge is mega cheap at the moment. I recompleted it recently - didn't enjoy it as much 2nd time around, but it's still a unique anomoly in FPS games. Well worth playing, no other game quite like it.

If you played the first one and your response to the prospect of a sequel is 'meh', I suggest you read some of the previews that have come out today. I think you might suddenly become interested in the game.
