Couldn't see this being posted by anyone else so thought some of you racing guys may be interested. Just purchased it myself as i thought it was a steal, lowest price I have seen this for is £19.99.
Here's some info on the game ...
Excite Truck is a spiritual successor of sorts to the classic NES motorcycle racing game, Excitebike. This fast-paced Wii truck racing game takes a few of the mechanics from the original game, but it largely strikes out on its own. What it gives you is a solid sense of speed and the often-thrilling feeling that you're just about to lose control of the truck and go flying off the course or slam into a tree. What it doesn't give you is a lasting sense of value, because unless you're bent on tracking down every single unlockable truck and racing against your previous scores to improve your rank, Excite Truck doesn't offer enough variety to keep you playing for very long.
Overall score 6.8 Fair (that was @ £39.99!) the average user score is around 8.1 whereas the average review score is 7.5. For a Wii game these days that isn't too bad!
