I just think that Forza Motorsport will be a good racing game for Xbox. Xbox hasn't had a decent racer untill recent TOCA 2 (and I do not count PGR series into decent races, for me PGR is decent and disturbing arcader), do Forza will be a nice welcome.
Still, everything I've seen is really far away from GT. No good angles, no good perspective, everything looks plastic. Driving model could be surprise, and I guess we'll finally get a decent force feedback wheel for Xbox with Forza, but I'm sceptic about lots of things regarding gameplay nad so. What I know is that Microsoft come to an idea to make a Xbox GT, but that is not enough.
I just think that they will not come to the right concept for the game, no matter how much they will try and work. So, I propose them to hire some of us from this place, give us a decent sallaries, and maybe we'll be able to come up with the right concept fpr the game before the relase date, because - from what I have read, they are just trying to copycat GT and/or add some features that GT doesn't have. From my perspective, all tthe features that GT doesn't have is for some reasons. And Kaz and PD are very certain about that reasons. And yes, damage goes to that reasons.
And one more thing: they are not living for that game. PD is living for the GT series for last 10 years. Kazunori itself for last 15 years. I guess that makes the difference in all the ways.
Then again, hope I'm wrong, I'd like to have another decent racer, no matter of the platform. But, It will just not happen, no way...
