Summary: The Single Player experience is phenomenal. Easily the best racing game I've ever played. The Multiplayer is absolutely atrocious. They removed everything great from Forza 2, and there is no matchmaking for any classes below 'A.' Also, if you don't have Xbox Live Gold, they screw you by removing ALL options from Free Play. If you don't have Live Gold, you have ZERO options when free playing a track. You will always do 2 laps against Easy opponents--ALWAYS.
Summary: First, the background. I played Forza Motorsport 1 and Forza Motorsport 2 (FM1 and FM2) on Xbox 360 using the multi-screen capability. I have 3 Xbox 360's linked on my LAN and connected to 3 HDTVs to provide a three screen wide view of the road and car. Yup, very cool, but I tell you this so you can see where I am coming from, not to be showy. Here is what I like about FM 3. 1. The added tracks make for more variety in this game and may make it appeal for longer 2.
Summary: While it's true the game has seen visual improvements, new tracks, and new cars, the longest-lasting feature that a significant number of players of Forza Motorsports 2 enjoyed, the custom online play, has been dramatically changed. The description, "In addition, the online multiplayer mode* gains an all-new game rules editor. This gives players a never-ending variety of ways to play with friends.
