Orange Box - for Portal, obviously. I haven't even bothered with the rest of the games in it yet!
Call of Duty 4 - The game is awesome, 'nuff said.
Eye of the North expansion for Guild Wars, but that was ok and not grrrreat. Guild Wars is probably the reason I have been saving money - I love it.
Uh... I guess I haven't been getting many new games this year. I got Vampire the Masquerade: Bloodlines and that was an AWESOME game.
