My partner and I finished it last year. We enjoyed it despite not being a big fan of the original system. I think the theme really helped and some of the new mechanics added in each session were creative. That being said it did take us a full year to finish it. We found it hard to table compared to other campaign games we were playing last year. We both preferred Clank! Legacy.

I’ve played gloomhaven, spirit island, and mage knight. Mage knight is the only one I found overwhelming and sold it after a few plays. I don’t have any interest in trying Oath or Twilight Imperium but the rest I’d like to play one day. I feel like this list is “popular complex games”, I’m sure there are larger rule sets out there.
