Oh Dear Lord....What Have I done?

[brute]

first you should try out:
-Bioshock-probably the best story in a fps ever
-COD4-one of the best multiplayer games ever
-Orange box-the best deal in gaming ever its only 40$ and it comes with 5 games
-Gears of war-very solid single player-and a good multi-player,online co-op makes this very fun
-forza2-hey your not gonna only play fps's and this is the best racer on 360
-oblivion-unless you own it for ps3 you should give this a shot,the same reason like forza 2,its not an fps and its awesome will last you months,so much to do here
-GTA4-possibly the best story in a 360 game,one of the best games of all time,superb single player,solid multiplayer definitely a must buy
i hope that will help you out
