Original Ninja Gaiden trilogy is great (I hate Ninja Gaiden II's stage hazards but still).

Super Mario Kart... eh, it's pretty average compare to the kart racers that came after it. It's not worth playing beyond curiostiy or nostalgia.

There is nothing wrong with Super Mario World but for some reason it doesn't quite click with me.

Battletoads would be a fun game if knew what the fuck it wanted to be.

Original Metroid? It's kinda jank and a pain to play without a map, just play Zero Mission.

Zelda's overworld can fuck right off, I swear it's only there to sell strategy guides. Dungeons are fun but if I already dumped 50$ on the game in the 80s only to realize there is no way to get through it without a guide or a magazine I wouldn't be super jazzed.

Tetris is a timeless classic.

Atari was great until 83, I think Activision's 2600 library hasn't aged one bit. It's all downhill from there, computers were the place to be for Western titles back then.
