The game quite surprised me, i played the demo and didn't think much of it at first. But after buying the game and playing it for a while, i was quite shocked. The gameplay is very fun and there are plenty of game modes to muck about in. The bikes handle very well and in my opinion the ATV's and Racing Trucks are not needed. The tracks are fun and the trick system is very rewarding. Also it's very easy to earn achievements, which is also a bonus. Although, it does have it's faults, for instance i completed the entire career mode in a mere 3 days. Also towards the end it can become painfully boring as you have to slug it out through a ridiculous amount of races. The online is bizzare as you have to have a full lobby to start a race, which means it's nearly impossible to play online.
Overall- A great game for those on a budget. It's very rewarding and great fun. And while there are areas that could be improved, the positives are greater than the negatives.
