Burnout Revenge and Gears of War.

Damn right. Loved the first modern warfare since it had nothing to do with WW2 and had a unique story to it. The multiplayer was great to play too, except for all the damn grenades.

Assassins Creed is a good game. It does get repetitive but what game doesn't? I mean all games get repetitive at some point.

Fallout 3

No sorry man, I wish I did to help u out. I have the same problem as u though. One of the tasks I'm supposed to complete is a left jab then a right kick to the head and everytime I do it, it doesnt register it as a combo. Any help would be appreciated.

Yes its worth the buy. If your a fan of UFC at all, u will like the game. Try the demo on XBL if your not sure about it.
