Forza Motorsport (Microsoft Xbox, 2005)

Forza Motorsport lets you own, customize, and race your favorite cars. You can collect models from more than 60 manufacturers and then race to earn money for upgrades and aftermarket parts. Test-drive your vehicle on various tracks, ranging from the challenging Nurburgring Nordschleife to the streets of Rio de Janeiro. You can even train your own "Drivatars" to use the same racing techniques you do, so they can race for you in competitions or train new drivers on your team. In addition to single-player challenges, the game includes multiplayer modes that are playable via Xbox Live.
