i tlooks idd nice, the valley looks kinda a BIG mix of coast, rally and desert.
the Canyone looks like a new type of deser, or kinda the the envi in the movie "cars"

if it became P2P, i am pretty sure many players would quit

i have done 2 3d models for TMUF,
and in 3ds max (and blender i think) it can be added a object called "camera". and if they made it so that the "cameraobject", was the head of driver.

should not be much coding to make it like that.
