Forza 2

forza motorsport is much better than grantourismo , we all know that gt graphics is better than fm , but what about the game play ? what about the tuning ( bumpers and this stuff ) ? what about the paint jobs ? and many many other things . the upcoming gt5 is the same gt4 but running on HD mode , they didnt add any more nesesary options and visuals like in the fm game ... which is : the damage ( when u slap into a wall or a car u can see the damage appears on the car also your car paint appears on the wall ..... and when u burnout and drift in FM u can see the rubber lines appears on the ground and that an important thing to me and gives more reality in the game .
GT was the best game BUT on the PS1 ( GT1 - GT2 ) those was great because at that time it was something new and we didnt see that kind of graphics ( 3d ) , it was a technology jump from 2D to 3D gameplay .
forza motorsport is the best driving game i ever played , i didnt say that because i hate GT or something , NO i have the both game's , and i played the both and end it , but i had fun with FM cause the gameplay is better ... its fun !!! what matters when a game graphics is gr8 but the game play is bad ? ;)

I have played both Forza 1 and GT4; what I can tell you is that GT4 has a great graphic but FM1 is WAAAAAY more realistic. FM2 will have like 10 times the mathematic equations FM1 had to define the behaviour of the car. So I'd rather say there is no way for GT5 to beat this game...
