I'm lucky enough to own a decades old Nintendo 64 and a handful of games, including the classic Mario 64. My kids love that game. Still, the first thing they asked when I showed it to them the first time is why the screen was letterboxed, why the characters looked like they were made of lego blocks, and why I needed weird cords to plug it all into the flat screen television. The answer to these spoiled monsters' questions, of course, is that the game is super old and wasn't meant to be played on modern televisions. It's the story of a lot of older games, though many PC games at least have a healthy modding community that will take classics and get them working on present day hardware. Consoles don't have that luxury.

Well, usually, that is. It turns out that enough folks were interested in modernizing Mario 64 that a group of fans managed to pull off porting it to PC. And, because this is a port and not emulation, they managed to update it to run in 4k graphics and added a ton of modern visual effects.
