Ok the point of the was to show how far the graphics have come in the three games. So before you post a comment like "Well, duh, of course Halo 3 is better, why are they even comparing", know that they're not trying to compare and see which is better, they're showing the improvements.

I think the switch from Halo 2 to Halo 3 is definitely a step up, but not as great of a step up as it was from Halo 1 to Halo 2

The memory stick was on the left before...so despite what the caption says, nothing changed there.
