halo-3 (aka halo2 minus everything that was in halo 2 that was in halo 1)
Everyone complains about graphics when really the only game that looks better on 360 is geats of war and thats because it only has about 10 characters on screen at a time. The explosions in halo 3 are brilliant and textures are crisp and clean.
Online is same as halo2 except new weapons and equipment.
All in all halo3 is the best game one 360 to date even if i can't score it better than I would gears of war. If you have a 360 buy it if you dont buy a 360 and buy this and cod 2 and gears of war.
