the graphics on the promo vids for forza 3 do look very good...
the thing with gt5 is only some cars will have damage which isn't a very good idea you can't put damage on some cars but not others. Admitidly the damage on forza isn't very realistic but its better than nothing
IGN spoke to a Sony representative at the Tokyo Game Show and he confirmed that all cars will support deformation, such as scratches, and mechanical damage, that will affect the performance of the car in a big way.
GB: Gran Turismo 5 will offer a new kind of damage…
KY: Right now we are adding a brand new real-time deformation engine that will process according to the speed and angle of impact. But doing this in real-time remains truly complex. We could make it an easier way with pre-damaged models but definitely we don’t want to make it that way.
“Night racing is going to be a part of GT5, but with things like dynamic weather, the choice is about whether it will improve the experience. The functionality is not a problem – we’ve got the weather system done – but if we are not sure about the quality of it, and how it improves the driving experience, we are not going to have it in the game.”
“Let me be clear on this. There is a massive amount of content in this game, I don’t think there are many teams that put as much into a game as we can. The launch of the game isn’t a start, we are releasing a full game. Everything we want to put into the game is on the disc when it ships. Having said that, we do have a sizeable online team that will look after it once it’s launched.”
