Nintendo also has some great couch co-op games,for example:
Mario Kart 8 Deluxe
Super Smash Bros. Ultimate
Nintendo Switch Sports
Super Mario Party
I also very much agree with the other commenter here, it’s such a shame that couch co-op is dying. The only ones still believing in it seem to be Nintendo.
Another game that’s fun to play is Unravel 2, but for me the Steam version had all sorts of problems so I ultimately ended up refunding it again.
