I don't feel like going downstairs to look at all of them. But I've got SNES, Playstation, PS2, Xbox, and an Xbox 360, so at around 10 or 15 games per console I've got around 60 games at the moment. The games I have for my 360 are:  
  
Dead Rising 
Madden 06 
NBA 06  
NHL 07  
Call of Duty 3 
Crackdown  
Gears of War 
Lost Planet 
GRAW   
  
I'd recommend all of them minus the Madden 06, NBA 06, and Lost Planet. Madden and NBA sucked compared to their last generation counterparts, and Lost Planet is basically a "Shoot this part of the giant bug and win!" game.
