Challenging
There are loads of challenging tracks and they are very unique! You will need lots of practice to get used to the controls but once you have learnt your prefered control setup you then have too learn the tracks, so when you enter a championship event make sure you have a practice run first!
Because every track is a challenge to play i find personaly it is quite addictive to play, allthough i do prefer the Moto events.
When you enter your career mode you can choose which events you would like to enter, to begin with you get MX, ATV and Moto events then as you progress through these races you will unlock more plus you can unlock new colours for you bikes/rider and the more you play the more points you will earn.. allthough you can just enter in the ski jump track and earn points by doing tricks which by the way are easyish to learn.
Because of the variety of tracks bike and rider upgrades and choices of game modes you will be amused for a while just trying to unlock everything.
All in all it is a good game but only if you appreciate MX style games.
