Well my list would be much bigger but in the last couple months I have finished about 15 games.
Right now I have
Gears of War Judgement
L.A. Noire
Dead Island Riptide
R&C All 4 One
R&C Collection
Witcher 2
Dead Space 3
Rock Band 3
Venetica
Borderlands 2 DLC
There have been a couple games I have been wanting to buy but I havent yet because of the backlog. So I guess those count as well. Which are
The Last of Us
Fuse
Ace Combat Assault Horizon
Starhawk
No where near the lists I am seeing in here though
