Also there are almost no good couch coop games, sadly.

I don’t mean you. But SquishedFly sounds like they where judging OP for not having all achievements. Which is why I answered originally.

Completely with you. But then it is not helpful, to also pressure each other online to complete stupid external stuff, when someone is clearly managing to just really enjoy the actual game.

Achievements are external badges without any value or meaning. If it wants you to do something you’re not having fun doing, why do it?
