I would be curious about your favorite coop games. I often find them a big lacking, often being a bit unbalanced. An example is Battle for Hogwarts, where one game can be a walk in the park and another absolutely impossible and rarely is there a balanced match.
I’m a big fan of the Forbidden series (in before the Forbidden Stars joke).
Forbidden Island is really accessible and a blast to play when you use alternate map layouts, they add a nice twist and lots of replayability to the game.
Forbidden Desert is a step up in difficulty and also a real blast to play.
Forbidden Sky is a but finicky but still fun to play.
Forbidden Jungle has not been released yet, but I’m sure I’ll have to get it to complete the collection!
