The N64’s notoriously poor video output exacerbated the characteristically blurry graphics even at a time when you could easily hook one up to a TV, which isn’t the case today.
The problem is how to play one on a modern TV. And while you could hook up four knockoff joypads to a PC to run an emulated version of Mario Kart 64, it wouldn’t be quite the same experience as the real console. Out of all of Nintendo’s home consoles, then, the N64 is arguably the one where it makes most sense to play on original hardware, particularly as many of its best games aren’t available on modern platforms ( GoldenEye 007) or just don’t feel the same without the original controller ( Super Mario 64). It hasn’t aged well, exactly, but it’s aged interestingly - you can recognize an N64 game a mile away. The controller was weird, the decision to go with expensive cartridges was weird, and the internal hardware was in a weird place where early texture filtering was possible even though storing and displaying detailed textures was not.
In hindsight, the Nintendo 64 was a pretty weird system.
