I have an old Raspberry Pi 1 (!) still going strong with Batocera Linux running NES, SNES and Mega Drive (Genesis) emulators.
I’m looking for easy multiplayer games that can be played with a 5yo. Non violent and ideally co-op, bonus points if somewhat educational.
Actually Sonic 3 is a slight improvement in this regard once you get the hang of things - Tails can be more helpful, and carry Sonic to higher ledges
