I did not write the following. Just using it to test.
Forza 2 gameplay operates at 60 frames per second, and replays run at 30 frames per second, due to their usage of post-processing effects. A hard drive is necessary to view replays. Using multiple screens, a player can set up and utilize a 180° forward view. It is possible to network as many as five screens and Xbox 360 consoles together to form a complete in-game view around the player, and a spectator view for watching gameplay live from the replay camera views.
Most cars in Forza 2 are fully customizable and can have up to 4,100 layers of graphics which can be edited with the livery editor to allow the player to add many shapes, forms and even pictures to their car.
The game supports split-screen, System Link and Xbox Live multiplayer gaming. Split-screen allows two player head-to-head racing, while both System Link and Xbox Live allow up to eight players to participate in a single race. Using Xbox Live, players can also buy and sell in-game cars through the game’s Auction House.
