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.
Nah. I played the crap outta Bubble Bobble around that age. Some of my best early memories involve playing Bubble Bobble on NES with my parents after dinner every night. Had all the level codes jotted down on a sheet of notebook paper, including all the lettered levels.
