okay brief comparison... motorstorm definitely wins on terrain deformation. i think the lighting and overall look is much better on DIRT. interface and presentation is fucking ace, best of this generation. graphically, they're actually pretty close. the amount of polygons DIRT is pushing is amazing, and wow @ the trees. the environments are fantastic, but the texture quality is a little lower than MS. gameplay wise, plays nothing like motorstorm, i like DIRT's gameplay better, definitely feels like a colin mcrae game and not nearly as floaty as MS. i think DIRT could be the best looking racer out right now for the 360, even visually better than PGR3 and Forza 2. there's still some slight screen tearing, almost zero in the first-person view --- but hopefully those kinks get worked out in the final game. overall, very impressed with the game both visually and gameplay wise, it holds its own against motorstorm and in some instances looks even better. but that's just my opinion.
