If you and your wife are into D&D-type stuff Divinity Original Sin 2 has local co-op. It's an isometric turn based adventure game. Super fun to play and on sale for about $18 at the moment, I think. I will say, it's a little more involved than some of the more casual games like Stardew, but if you're willing to put in a little time to learn the game it's one of the most rewarding games I've ever played.
My girlfriend and I actually played through the whole thing together!
Same here! Good news is that baldurs gate 3 is coming out on August 3rd - not long now!
