Could be better!
The first problem is that when starting playing the game, it forces the player to play the only two available tracks over and over again until reach level 10. When that happens a lot of tracks become available in the game. It took me less than 1 hour to do that, just set the racing difficult to rookie and 3 laps. After you unlock the other tracks from reaching level 10 you can play anyway you want, but this is the easiest and fastest way to reach level 10.
Second problem is that there is no carrer mode. That's preety sad, you just race around the tracks unlocking new gears and reaching new levels.
There's a vertical splitscreen feature that works great. I always find this useful in the games because I like to play local multiplayer a lot.
The racer and motorcylce gears customization are good enough with plenty of brands.
Graphics are very good and controls are fine too.
There are some avatar awards too that can be unlocked just by playing the game.
Overall I liked the game but I reccommend trying it first before buying.
