My SNES recommendation list would be like this:
Final Fantasy 6/3
Final Fantasy 4/2
Earthbound
Zelda: Link to the Past
Secret of Mana
Soul Blazer
Mega Man X
Super Mario World
Super Mario RPG
Super Metroid
Shadowrun
Legend of the Mystical Ninja
Super Punch Out
There are others beyond that. Everybody loves Chrono Trigger, and it's definitely worth playing as an RPG, but didn't captivate me the way FF6 or the others on the list did. Just personal preference. Donkey Kong Country as well, the graphics are weird to modern CGI eyes, but it's a fun platformer. I just don't love it as much as other games on the system. I also like Uncharted Waters New Horizons, but it might be too slow for a lot of people. Same with Harvest Moon, I loved it in 1997 but it was very underdeveloped and after the N64 and PS1 versions came out, the SNES one is borderline unplayable by comparison - and definitely too slow and strategic if you want to breeze through the best of the SNES and other systems. I also never really got into Star Fox and think it's aged poorly anyway. Wing Commander is what I'd recommend for a space shooter. Kirby Superstar is fun but more a collection of short mini games than a fully developed game on its own right. Lastly, Super Ghouls n Ghosts is one of my favorites but I would only cautiously recommend it since it's notoriously difficult to get a handle of the controls and platforming.
