Since its inception almost five years ago, the Forza Motorsport series has been Microsoft's answer to Gran Turismo. With its extremely realistic driving physics and huge selection of real world vehicles and tracks, Forza has offered the best simulated driving experience gamers could find on a non-Sony console. As the series has progressed, it's seen a shift of focus toward customization, and a huge community of talented designers has sprung up around the game. The newest entry, Forza Motorsport 3, further expands on the customization modes, but also makes great strides toward making the series a more inclusive experience. While the new changes may cause some of the hardcore players to scoff, most players will find a more robust, accessible, and exciting racing sim.
