I can understand this sentiment for 8 bit games (they largely haven't aged well) but for the 16-bit stuff? That's classic gaming at its golden age. The sprite-based graphics hold up incredibly well - arguably better than the generations that came before and after it. People are still making sprite-based games and trying to make them look as good as they did back then. To this day I still haven't played a game as good as Link to the Past, Chrono Trigger, or Super Mario World.
I have one too, and it's surprisingly easy to mod the thing. I plugged it into my laptop and within five minutes I had Chrono Trigger, Turtles in Time, and other missing classics on the machine. If you want more deets, lmk.
I'm also through my first Earthbound run, and I think I'm enjoying it way more than I did back as a teenager. Guess I'm more appreciative of the gameplay and narrative now.
