I agree with Rassilon 666
, to me GT4 will be way better, car damage or not, some people here probably never tried the game to say it sucks or maybe just cause it's on PS2
...what when GT5 comes out with car damage then?What excuse?
The physics in GT3 were amazing and they managed to improve it.
I played the Forza demo with great hope and so far (to me of course) the game has no chance to compete with Polyphony's title...but I understand you guys, I am a xbox fan too and I have been waiting for a real car sim for years now (and I expect much more from GTR actually).
Second point is the force feedback wheel, of course it's important, try out the Logitech 900° FF wheel for GT4 and you'll be begging for such accessory to come out for the xbox + I dont have that feeling of a "centered wheel" for Gran Turismo unlike the Colin Mc Rae Rally series...
Like themadman123 said, if GT4 was out on the box, there is no doubt we would all grab it...Forza 1 can hardly be better than GT4.
