I need to add an addition to my collection

Ok, I want to add a new game to my collection, and i really want a game that i can beat, not a sports game, but I also want a game that is great on Xbox Live. Well let me give you my collection: Gears of War, Condemned, Oblivion, FIFA WORLD CUP:2006, Madden 07, Fight Night Round 3 and all 3 Burger King Games.

If ur looking for a fantastic game online and offline may I recommend Rainbow Six: Vegas

If ur lookin for a game that isnt as great online but sure delivers a punch may I recommend Saints Row

hope that you choose a winner
