The game centers around a career mode. You start at an Amateur in the 125cc class and work your way up to the 125cc Pros and then the 250cc Pros. Along the way you can take part in freestyle competitions and tutorials to hone your skills.
The tracks are varied and can be quite long, which makes for fun racing. However, the game as a whole is quite short. I was able to complete the game within 3 days and it doesn't offer much in the way of replayability because there are so few team/bike choices. Also, features such as qualifying races (and last chance qualifiers) are completely absent.
Overall I found Supercross 2000 for the N64 much more enjoyable. In particular it had running commentary during the races and multiple camera views. MX 2002 has neither of these.
I recommend renting it for a couple days of entertainment.
