If you like FPS games, might I recommend Borderlands 2. It's got a lot of personality for a game. They basically took a FPS and Diablo and put it in really cool world that's got some strong nods to Mad Max/Road Warrior. It's all about getting cool guns and grenades through killing stuff. Solid writing and great voice acting. It's got loads of replayability. It's not a deathmatcher like most FPS games. This game is all about CO-OP play. The more people in the game, the tougher the baddies get and they throw more at you -- the reward is better loot. I highly recommend this game.
