I had it a few years ago in the Wii's formative years. From my memory it was great fun, the emphasis on tricks meant it wasnt just about winning but winning in style - pulling drifts and airtme got you stars, which counted towards your victory as well as position - and you got boosts for tricking and drifts etc.
Also, the custom soundtracks work a treat. Just shove MP3s on an SD card and you're away.
It's probably aged a bit by now (I no longer have it) but it was great fun back in the day and a fair few events to beat.
