I'm glad they focused a lot on the backround graphics in this version also. That seemed to be an issue I found with FM3. The mountains and everything look stunning! Along with the cars of course but nice pics show a little more than gameplay.
Also quite happy the cars actually blend with the enviornment rather than stand out like in Forza 3.
If anyone watched the trailer, one of the manufacturers that is shown is the one that created the Warhog replica. Thrown in there for an "under the radar aanouncement"? For fun? Who knows...
