Yeah that’s the only way I’ve played co-op for Minecraft, on the couch. We had a good run of playing ARK together like that for a bit as well. But the controls for co-op have a few issues. If you go to the inventory or upgrades, the buttons for the other player will start to get wonky in their inventory or upgrades. Usually you all together can’t press buttons at all and have to exit until the other player finishes. If you look through a scope, it zooms on the other person’s screen as well, strange flaws that you would think they would have fixed but never did after many updates. Almost forgot. You might get yanked across the map and drown or not be able to see underwater if the other player gets to far or isn’t in the water. Think they fixed the water thing now, haven’t tried it yet though

But if you have a PlayStation, a short game that I really liked was “A Way Out”. Its a couch co-op jailbreak game. It was made really well I think. The screen even resizes giving each player “priority” parts where it intentionally makes one player take the lead and the other support. Never played another game that did co op so well.
