I got this game Friday and have never played a game so much!!
I've also got GT5 Prologue on PS3 and have shelved that for this baby :0)
The depth and design of the game is superb. The graphics are very good BUT I have to say they are not on the same level as GT5.
From my perspective however, it's about the complete package. This is where Forza 3 excels....the physics of the cars, the campaign, the online experience and the tuning/customisation. I just can't put the game down!!
Well done Turn 10 and roll on Xmas so I can get a proper rig i.e Playseat and new steering wheel :0)
