I actually own this game and have for a while. I've played pretty much every course and this game is a blast.
It got some really good characters to use, the game play is pretty sharp, with a few odd things here or there. The game is realistic enough to make it fun, but arcade enough to let you land on flat ground after falling about 500 feet. No bike in the world has suspension that good.
It a bit old now, but even still, it's a great game. You can unlock sponsors in career mode and earn money for races and tricks. You can us it to unlock all sorts of things. One of which is a sheep to ride, rather than a bike. It also features a deer an a llama.
This game is a blast, especially with more than one person, and even alone. I definite rent or buy.
this game is amazing the graphica are the best ive ever seen if you dont get this game you r making a mistake. i played this game all the time at the video store and when the stopped selling it i acually cried. i fell in love with this game and stopped eating for a week. so my parents had to take it away jk but it is fun ;)
