Curating a small SNES/Genesis collection: must-play 16-bit titles and hidden gems.

[EvelynC]

I recently dug out my old Super Nintendo and Sega Genesis from my parents' attic, and I'm looking to rebuild a small collection of cartridges. I want to focus on the best retro games that still hold up today in terms of gameplay and design, not just nostalgia. I have classics like Super Metroid and Sonic 2, but I'm interested in hidden gems or titles from that era that I might have missed as a kid. What are your personal must-play recommendations for the 16-bit consoles that offer a genuinely rewarding and fun experience for a modern player?
