Quake 4 (Xbox 360, 2005)

This game adds the playability and better showcases the graphics that was missing from Doom 3. Quake 4 has a feel of Starship Troopers (the movie not the game, which was poor) and the old run and gun is expertly executed in this title. While it adds nothing new to the FPS it certainly makes up for it in a polished updated version of the genre that will entertain for more than a few hours. The atmosphere is enhanced by the marines around you which gets rid of the lonesome feeling you get when playing some fps, while not as full bodied as the call of duty titles, there is an essence that you're not the only one fighting this war. The enemies are intelligent, and will dodge fire and you're allies, the marines, are not the cannon fodder that normally populate these types of games. For my liking there still isn't enough open air combat, but I'm not far into the game as yet, and that could change....but I'm beginning to think thats unlikely.
