I think that they should stick to the graphics made by the game engine because then people, including me, would know how good the graphics were of the game we would be buying. I mean, if you made a trailer using, oh... say 1080p resolution, and the highest resolution the game could support was 720p or 1080i, you see the trailer, buy the game, and then see that the game looks nowhere near as good as the trailer, then you're S.O.L. Not that that would happen with Halo games, I mean , I would buy a Halo 3 even if the graphics were 8-bit nintendo games. Anyway, they should make the trailer using a normal 360 graphics engine. Thanks!
