Super Mario Kart is easily the worst Mario Kart but it is far from a bad game. My biggest recommendation for this game is to give it some time to learn the controls, once you do this game can be fun. I should also mention that the CPUs blatantly cheat but there isn't much they can do if you just keep your acceleration going.
My favourite tracks are Rainbow Road and Mario Circuit 2 while my least favourite track is Bowser Castle 3. Music isn't super crazy but I do enjoy Koopa Beach and especially Rainbow Road.
Give this game a fair shot, it paved the way for future kart racers.

Played on the Nintendo Switch. Got gold on the first three cups and silver on the fourth which is good enough for me as far as a win condition goes.

It's solid and I certainly respect it for laying the ground work for one of the biggest racing franchises of all time. That said though, it only has like maybe 4 great tracks and the rest are either kind of good or just okay. Some of the music is really fun and intense but others are kind of repetitive and annoying. The sound design can also be grating at times. It's certainly good but it doesn't get anywhere past that and it may not be one I am in a rush to revisit. 7.0/10
