I would love to see more games that support a mix of player capabilities. Like how in Child of Light a second player can do supporting, fun, low stakes stuff alongside the main game. My kid loves to play with me, but 6 year olds are bad at games.
Couch co-op on PC is great if you have a laptop and some controllers. Bam, better console than most consoles thanks to emulation (any potato will run up to PSX nowadays), but also games like EDF 4 or 5, Broforce, Assault Android Cactus, Human Fall Flat, Party Animals, Overcooked and a bunch of others
Just make sure to use "Game mode" if you have a "smart" tv, though visual lag might still be a hassle (from my limited experience, LG smart tvs will always have at least 100ms of lag, even in game mode and all image processing features turned off)
