Simplification doesn't necessarily mean you're making steps backwards, the opposite is the case. Of course you need a minimum of complexity in a simulation game as you're trying to do nothing less than coding real life physics into a piece of software. A 5 point contact model is better than a 1 point contact model. Just to be clear. I'm not saying 'throw everything out of the window and make Trackmania type of tyre physics'. I think the argument is that you don't need to re-build every aspect of reality in the game. As an example you can look at how people started flying without doing it exactly as the birds do. It is much easier to just have some kind of propulsion and use lift. If you can get a similar or even better result of realistic tyre physics with a simpler method without compromising the physics itself, then that is probably what Einstein was meaning. Overall simulation games will get more complex as the tech will get better as well, but maybe you can optimise certain parts by using a simpler method. Optimisation through simplification if you will. Anyway, I don't want to talk down what Reiza's doing, AMS2 is amazing and I love it!
