if you have a XBOX 360 you have to own Halo 3 ! it be a incredible game both in game play and graphic . it be clear that XBOX want to make this the feature game just like Mario be for the Nintendo . the game be easy to play and have several difficulty level . I find the game challenge enough on the easiset level and be able to beat it even move up a level . however the most difficult level be just to hard for I -lrb- I be a very casual gamer -rrb- . this be my favorite out of the 3 halo , my only complaint be the game be too short .
