FMX Team - Time Waster
FMX Team has one gimmick, which is that you have a stable of three riders to choose from, and you can not use any one rider twice in a row. I found the #2 and #3 riders to be the most useful due to them both accelerating faster than the #1 rider, even though rider #1 has a higher top speed.
To get a high score, it seems that you need to find a jump where you can sit and perform flips and tricks over and over again without advancing through the level, but then make sure to make it to the end before the time is up. But if you're not too worried about getting a high score, and just want to have a fun quick time waster, FMX Team is worth your 15 minute coffee break.
