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’ve played a lot of Betrayal. I play tested it at AvalonCon back while I was in high school.
It’s very random, and has the potential for some really great games and some real duds. I know in the later editions there have been efforts made to tighten up the scenario balance, do maybe things are better. But From my experience, maybe 1 in 3 games has been ‘good’, 1 just meh, and the last a steamroller for one side. So many of the scenarios depend on thr size of the house, with too large or too small of a house making it unbalanced. Or specific items being useless or over powered. And many of the scenarios have pretty loose rules.
As long as you understand that, it’s a fairly light game that can have a decently large group working together.
I’ve enjoyed my copy, but there was a stretch where it was OOP and going for big money. It wasn’t worth that, but for a regular in-print price, it’s fine.
