Disclaimer: I played through this game on the N64 15~ years ago. The races are fast in the beginning, and super fast in the last half of the game. You can buy upgrades (speed, traction, brakes, cooling, etc.) from the shop with money you earn from the races. New vehicles are unlocked as you complete the tracks. It's a super fun game, but at least I managed a "complete" (all tracks beat #1, all money spent on upgrades) playthrough in less than 4 hours, after which you have nothing else to do but beat your own track records. I had strong nostalgia for this game, but it was suprisingly fun, even after seeming a bit simple in the beginning. As the races get faster and faster, the gameplay really sucks you in. The tracks are good and vary nicely, and the atmosphere is great! Due to the very short game span, I'd say it's well worth around 5$, more if you have have old nostalgia left for the game.
