The game is pretty good, once they release a patch it should be very good. just a couple big bugs that prevent you from enjoying all the features.
1. bug with the development upgrades, once you reach a certain level it will corrupt your save game file and when you try to reload you will have to start all over.
2. the game does not show up on your xbox gamerscore for other people see that you are playing the game or what achievements you have unlocked.
Other than those two things the game is pretty good, you just have to play an entire season through in one sitting or you will loose your standings. I had 11 wins and turned the unit off and when i came back received the corrupt save file message. restarted and saved after 5 races and received the same message.
