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 see a few of my favorites have been mentioned already (Aeon’s End, Spirit Island, The Crew, Pandemic Legacy) but here’s a few more:
Gloomhaven: There’s a reason this game was at the Boardgamegeek #1 spot for years. Absolutely an epic game, with so much strategy and variety involved. For those who are intimidated by the complexity, size or price of the game, there is also Gloomhaven: Jaws of the Lion, which is essentially a light version of the game. An excellent starting point, and not any less fun than it’s big sibling.
Oathsworn: Into the Deepwood: Another big campaign game with very interesting mechanics. The game is quite hard and punishing, but you have lots of difficulty levels you can play on. The story is set in a land overrun by the Deepwood, a forest filled with huge monsters. You play a band of mercenaries who defend people from those monsters.
Sprawlopolis: A game consisting of 18 cards, that contain city blocks and roads, and each player places a card down to add to the city. Each card has a different scoring system on its back, and you draw a few for each game, so every game feels entirely different. Quick to play, and fits in your pocket so you can bring it anywhere.
