Street Fighter IV
Borderlands
Plants vs Zombies
Assasins Creed 2
Shadow Complex
Prototype
DJ Hero
Modern Warfare 2 (kind of)
NFS: Shift
Batman: Arkham Asylum ( Kind of got bored towards the end)
Lumines
Fight Night Round 4
My favorite game of last year would have to go to either Shadow Complex or Borderlands. Two games that brought the fun back to games.
I will also say that Plants versus Zombies stole more time from me than any other game in the month of December. What an experience.
