Halo 3 Graphics Evolved

GameSpot writes:
Sometimes it can be easy to forget that the original Halo and its sequel Halo 2 both came out on the same console, the original Xbox. The Bungie development team was able to use its experience with the platform to make Halo 2's graphics superior to the original even though both games were designed for the same console. The graphics leap from Halo to Halo 2 was impressive, but it also raised our expectations for Halo 3. If Bungie could make Halo 2 look that good on the Xbox, just imagine what Halo is going to look like on the Xbox 360.
