Got RetroArch setup and working, got a controller, got PS2, N64, SNES emulators currently but likely get all old systems at some point. Recommendations for games you found worth goong back to?

Ive been loving this game. Its a card game with lots of depth to the optimization and some RNG but its not overly punishing. If youre looking for a fun casual game try it out! Its less than $10 on sale right now.
