Either kids games or 2 player games for both of us.
This is what I recommend :
World of Illusion !!!! (right on the pic)
It's a 2 player game, playing this with my kid a lot when he's 4 years old.
He's now 10 years old and more into Minecraft and Roblox,
but sometimes once a month we play this game together just for nostalgia sake.
Also my other recommendation
For your kid : Ecco Jr, Sesame Street: Counting Cafe, Tanglewood, Mickey's Ultimate Challenge
For you : Shinobi 3, Streets of Rage 2, Phantasy Star IV, Aladdin, Quack Shot
