GT4 has a hell of a lot of nice things yes, Forza offers you the chance to tune your car how you wan't. I'm not much of a fan of rice kits but Forza offers people Aero kits as well, you have the choice.
So 1-0 to Forza.
Decals, these are found on race cars as also seen in GT1,2,3,C,4
![Tongue :P :P](/wp-content/themes/gtp16/images/smilies/tongue.svg?v=3)
and GT4 so if you don' like them in Forza you can't like them in GT4 either, however Forza allows you to create your own race car complete with your own selection of sponsors and decals.
2-0 to Forza.
Improved physics model has been implemented, how it will translate into playability in the final build we don't yet know so that has to be a no score draw, the same should be said for the AI.
Still 2-0 Forza
Tuning and setting up your car in Forza is quite a lot deeper than in GT4, and to me thats important, you can change and set loads more stuff in Forza.
3-0 to Forza
Graphics, orzas are better technically, pushing more poly's and so on, GT4's have a more real look to the thats a draw.
4-1 to Forza.
Forza has 8 player online, a huge plus to me and promises many features including online trading and car clubs ect.
5-1 to Forza.
I have so much respect for Gran Turismo but when a game with more promise is shown I'm no a PD lap dog I'll get interested in that new game.
