The screenshots posted are too hard to see the difference that is clear in real person playing the game. Forza2 is a great sim, from what i heard it has a very indepth tuning aspect to the game along with other great sim features.
But there is one thing that puts the GT5 beyond Forza/PGR and that is the great car models used, GT5 uses cars models that are over twice the poly counts of the 360 games and thats a fact. The first person view is insanely better in GT5 then the other ones from videos i've seen on GameTrailers.
Forza is a great game it just can't compete with GT5 in the graphics.
