Call of Duty 4 with the essential multiplayer experience on the system. After playing the newer Call of Duty 5, i can still say that i prefer it's predecessor much more. expect to loose a lot of hours blasting your way through european soldiers. this one is a winner.

Halo 3 might be a bit of an acquired taste, but it has a very loyal fan-base. it's light-heart fun and is easy to jump in and out of.

Bioshock is an incredibly deep and engaging shooter that faces players with a lot of decisions. the characters are incredibly realized and its atmospheric and eerie tones make it a lot more like a movie than game. i had a lot of fun with this game, but a lot of people might not appreciate its subtleties.

The Orange Box offers the best value of any game on the market. it includes the legendary Half-Life 2, it's two fallow-up titles (Ep. 1 and Ep. 2), Portal (excellent puzzle game), and an in-depth multiplayer game called Team Fortress 2. the fact that the graphics might not be up to par with most modern day games, but it really makes up for it with smart, innovative game-play.

my oddball choice. Soulcalibur 4 is the fourth entry in my favorite fighting game series, and does not disappoint. if you enjoy 3d fighters, this game won't disappoint. plus, you can pick Yoda, which is pretty sweet.
