Mirror's Edge AMAZING graphics, very immersive & intense, but very linear and short.(though time trials add some playtime)
Prince of Persia Amazing fun acrobatics and fighting until you have to go orb collecting everywhere you've already been..
Dead Space great graphics, scary as hell, gory, but has some backtracking..
X Blades anime chick in g-sting ftw? (very very very repetitive action)
FEAR 2 I haven't played it, but apparently its quite impressive compared to the first one.
Pretty much the only games that you don't have, and are worth mentioning, imo.
