Bad Company Battlefield 2 is pretty sweet man. Great FPS for sure.
Alternate suggestions: Star Trek, The Sabotuer, Prototype, Final Fantasy 13, GRID, or even COD MW2.
If you have an opportunity to buy a PS3 God of War 3 has been stellar from what I've seen.
Edit, forgot about Dragon Age Origins. It was an epic release and near rival to World of Warcraft.

2nd Edit, Totally forgot about Borderlands. Great FPS with a touch of RPG. About a 20 hour experience in single player, not including down loadable content.
