There's really solid gameplay here. What holds Mario Kart 64 back is that it's pretty barebones. Four cups, eight racers, a couple game modes. What helps this game stay relevant is that every single course is a banger and the mechanics are pretty solid. That helped the game win it's reputation and to keep it even as arguably better sequels have come out over time. People still play Mario Kart 64 even in the face of the shinier new entries and that is a testament to it's quality. Also, it has some of the jankist graphics of any Mario game and that's sort of fun. If you're playing Mario Kart with a group whose willing to try one of the older entries this is probably the go to.
