Played the game for 20 hours and I don't feel about playing it more. The game idea is great and could be done better than that. IF the game was released in the mid 2000's i guess it will have a better success chance. The first race of the game is a time trial you have to finish 5 laps under the time limit the faster you finish the more chance that you'd get a golden medal and upgrades on the second level you race 8 oppoments and who ever finishes first gets the golden medal. you can fill in your nitros guage by doing flips in different directons. the longer the flip the more boost you get. you can also get different engine bodies and customize your car paint mirror etc but it's not that easy, you have to earn some medals before unlocking this feature. I havn't tried the multiplyer yet. Going to give it a shot later on.
