Lack of content as in not enough tracks?
I think it pushes credibility as much as the E3 trailer. The E3 look was maintained, but not the fidelity. This trailer shows individual blades of grass! I doubt we'll get there. However, for a first gen title Motorstorm didn't do too badly against the previs, so I expect in essence the game will be very similar. Of course the look will be totally different when you're actually driving, so it'd be hard to match what's attained with what was shown here. I mean, if the camera never gets close enough to the ground, it won't matter if they are rendering individual blades of grass or notIm in too minds about the visual's, one half says to me "remember the E3 CGI trailer" and the other side of me says "Look at uncharted"
It is CG of course, I've seen the script months ago when we've been contacted about the project - haven't done it though, too busy with other stuff.
