Mirror's Edge got kinda mixed reviews ( mostly in the 7 to 9 range) but it looks hella cool. I may pick it up after I can afford it after some other top ranked games, and I beat a few of the ones I already have. So many games, so little time.
Theres a free demo of Mirrors Edge on the Playstation Network. A lot of people like Call of Duty. Mirrors Edge sounds like it has some flaws but a lot of people will look past that and like the innovation of it.
