I don't even know how to start. I can't think of a single game that's as playable and replayable today as it was back in 1996. the controls are absolutely perfect. Mario handles so effortlessly that someone with no skill can have fun just moving around with him, while an expert can do some crazy shit and pull off amazing stunts to beat stars. the atmosphere was perfectly crafted for the limitations and still has some of the most iconic tracks of video game history. it's also the perfect speedrunning game. there are so many different ways to speedrun because of how versitile the controls are and how open the levels are. It's more than just an important game that changed the way games were made forever, it still holds up on its own today and holds it's rank as my favorite video game of all time.
