What are some good xbox 360 exclusives OTHER THEN HALO OR GEARS OF WAR!?

[Braxton J Carter]

i really need to know because i usually just get halo 3 and gears of war. ( im not a sony or wii fanboy but im just asking) as many xbox 360 players tell me oh halo 3 or gears of war, but i need some other GOOD exlusives, that you would compare to either a wii exclusives or a ps3s.
i understand what your saying Creath but Ps3 wil be getting MAG ( Massive Action Game) it was revealed at E3 and you must see it! 256 players online! in ONE game, in ONE big map.
