With a new physic's engine, new tracks and 1200 cars it should be sweet. It sounds like all the cars from GT5 will be in the game so unfortunately lot's or MX-5, RX-7, Skyline etc doubles again but the new cars coming to the line-up should make up for that. I'm really hoping that if Mount Panorama comes to GT6 we get a good selection of V8 Supercars.
I've had a quick play on the GT6 Demo today. First impressions are that the physic's is defiantly improved over GT5. You get a lot more feel for the weight distribution etc with the new engine. I'm looking forward to seeing the new damage modelling. Tyre squeal sound is improved and helps a lot judging grip. The force feedback delivered to my GT5 wheel was really nice. A lot better than GT5. I also went for a spin using the PS3 controller and found that that too has a big improvement. In fact it is not hard to go nearly as fast with the controller as it is with a wheel. I did notice that some of the textures outside the track at Silverstone don't seem to be quite finished. That's about the only flaw but they'll be sorted before release so no big deal.
Bring it on and thanks for the bonus T-Shirt Mighty Ape. I haven't seen that included anywhere else.
I'm looking forward to getting this game.
