Well recently the Forza 4 demo has been released on the Xbox 360 and while playing the demo, I am quite excited for the game now. I had pre-ordered the Limited Edition of the game and can't wait.
The demo allows you to pick 3 cars which are the Mercury Cougar, Subaru WRX and a Ferrari 458. All cars sound great. That is something I like from Forza than GT5. Even the cars in this game look so much better. Definitely better than Forza 3 and GT5.
The environments and the tracks look so good. This is what GT needs to get for their environments. The track you play is in the Alps. I forgot the name. Anyway, depending on which car you choose, the track is changed into another format of the track. I hope you know what I mean.
The cars feel a little bit different to Forza 3 which meant all cars felt the same but I think Turn 10 has fixed that. There Physics engine won't be as good as GT's engine. I can say that but Forza 4 is looking like to be a great racing game for racing fans and gamers. I can't wait to get my hands on the game.
