I guess one of the best compliments to PD's artwork is that people keep thinking that the Eiger mountain in the track is a picture, rather than a 3D model (which it really is).
or calling those cars pre-rendered
Forza2 of course will have the best physics etc. but it still doesn't have that "uncanny valley" look that GT does. IMO
Says who ? the only thing Forza may have over GT5 will most likely be damage models and customisation.
