The pinnacle of the kart racing genre and the first video game I ever played. The boost mechanic and physics are top-notch and this game is filled to the brim with content in comparison to other racing games at the time. All 16 tracks have wonderful designs and are fun to race on and fit well with the game's story mode. While I think Diddy Kong Racing has the better adventure mode, this game's story mode is still pretty good and it is fun to explore the hub world and race through the 16 tracks it takes to get to Oxide. In terms of unlockables, this game has a ton of them. You can unlock every boss character, Fake Crash, and a track called Turbo Track from playing the story, N-Tropy from beating his time trial ghosts, and Penta Penguin by inserting a cheat code in the main menu. You can also unlock a handful of battle mode stages but I don't remember how you do so. Not only was this game a phenomenal competitor for Mario Kart but also one of the best Crash games in the series.
