Just as in Forza 2, Forza 3 offers players a huge number of online options. Players can compete in all manner of events. Some events are realistic, such as the racing, drag, and drift modes. Forza 3 also includes just-for-fun modes as well, such as several game modes which are variations on the game of tag. The various game modes go a long way towards making Forza 3 all games to all people, and a good game cat and mouse is just as much fun as a white-knuckle race.
The community features are there, as well, and have been improved upon with a few new options. One big improvement is the vinyl editor. Forza 3 uses layers of shapes, called vinyls, to paint cars. In Forza 2, these could be only be edited on cars, so it was hard to make ones which could be applied generally to any car. Forza 3 fixes that. It also uses a more logical and easier to navigate storefront system with enhanced search features.
Even the multiplayer lobby is more logical and easier to use. The only real flaw is that Forza 3 has shipped without the ability to search for any class of race below A class. This is an odd oversight, as many people like racing the less capable cars, but there are rumors that this will be patched in the future. In any case, it is only a minor flaw in what is otherwise a multiplayer experience easily on par with what Halo 3 offers for shooter fans.
