I would advise you to watch some clips of Mach rider before you purchase it.
I like it but it can be quite frustrating in the beginning if you don't read the instructions on controls and hud display.
I happened to not read the manual so I was a little aggravated from crashing so many times. Then I noticed on the hud that there were these 1,2,3,4 numbers and I thought "hmm these must be gears to make me go faster", and they were so.
I would say that this game is the F-Zero (and a little bit of Road Rash too) of the NES generation, except you have only 1 bike and one character to choose from lol.
Oh and you can shoot (lasers?) the other bikers or canisters that are laying around, you can also bump the other bikers against the canisters or other obstacles, there are oil and water ponds so you may slip and crash but you can still survive if you're lucky or good enough.
There are 4 modes: Solo, Endurance, Battle, and I think that in the other mode you can create your own tracks.
