Instead, Forza is about maths: it's about throwing numbers at everything from the way light hits your car to how your tyres flex.
When new Brit studio Playground Games started work on Forza Horizon they did it with Greenawalt's vision in mind, but with that maths as the foundation. That's how, in just two years, Playground have made the best-looking and best-handling road racer you'll ever play. While Microsoft's demo pods at E3 are running just the one car - the new Dodge Viper - with every possible assist turned on, you can play Horizon with the full Forza 4 handling model, or with any setting in between. Every car has been custom-tuned for on-road racing, but that's as far as Playground have gone with simplifying Forza's raw science.
