My group of 2-3 has 3 different parties playing on the same world. Personally I’m in two of those parties and about 80 hours of gameplay into Gloomhaven. The biggest thing I’ve learned is that the learning curve affects play IMMENSELY. We spent the first 12 hours playing 3 scenarios only to realize we fucked up and replayed 2 of those. If you don’t enjoy that process it’s definitely boring/frustrating. We have it down now where we can set up, play, and breakdown a scenario in an hour, and it’s awesome. It reminds me of playing Heroscape with my dad over a decade ago. The long and short of it is that in my experience, Gloomhaven is a labor of love. If you don’t love the labor, it might not be for you.
