Ehhhh... The plot in gloomhaven is really pretty minimal. It's a matter bones choose your own adventure stringing together episodes in a fun combat tactics game.
The problem is that some of the retirement quests depend heavily on the plot structure - "kill 5 bosses" can be 20 scenarios or 5 scenarios depending on where you are in the campaign. Similarly for some of the monster-specific quests; some even become impossible if you get them too late and don't want to replay old scenarios.
I think it would have been better as 8 starting classes, 8 unlockables, and two more compressed campaigns with some other progression compressed accordingly.
