We had a lot of fun with this game. Racing against the computer-supplied opponents (how many of them are there anyway? ;-)), tripping them, landing on them. When we weren't racing, we would just sit there and knock over racers hoping to get in that spot where we could keep them down. After a crash it was hilarious to sit with the motor turned off while the crowd roared with concern/excitement(?); then after a few moments...start up the motor!
It was also quite fun just to watch the little guy run back to his bike — which happens quite often when you try to see how long you can do a wheelie before falling over backward!
Building a custom track was fun, putting all the cooling arrows and high ramps in one lane,
watching the computerized oppontents stumble into our pit falls.
