Kirby’s Adventure just feels the best to control. I don’t like the way they changed how powers work in Superstar, and I think the variety, controls, and level design aren’t as good. Sometimes, more isn’t always better.
FFTA is the best in the series, but it’s also the most unique story. FFT is still the usual “fantasy” universe you’re familiar with, but there’s an interesting element of isekai in FFTA.
Battletoads is hard, but not impossible. Everyone remembers the third level with the bikes being a pita, but I did it as a kid. Tip: towards the end, there’s a part where walls will come at you faster and faster, but if you try to stick to the middle and move just enough out of the way, you can weave back and forth. Don’t overcorrect; light touch. If you get really good, there’s even a secret in that part that lets you skip several levels. Look for a sparkle!
Little Nemo is based on a comic, and it’s a really unique puzzle/action platformer. I haven’t played anything quite like it, but it was one of the first NES games I owned.
Mega Man 2 unequivocally has some of the best chiptunes in any game. There’s a reason there’s so many remixes on OC Remix just from that game.
Starfox 64 is the original SNES Starfox but with better graphics, gameplay, and story. There’s also multiple endings…
