2009 List, in no real order tbh.
Batman: Arkham Asylum
NHL 10
Kingdom Hearts: 358/2 Days
Call of Duty: Modern Warfare 2 (yet highly overrated)
CoD: World at War's Nazi Zombie maps
2010:
Final Fantasy XIII
Kingdom Hearts: Birth by Sleep (I'll likely buy a PSP just for this game)
NHL 11 (ha!)
Arkham Asylum 2
Red Dead Redemption (could be 2010 game of the year if it's done correctly)
