I personally rarely like premade content. I like sytems and rules and some stuff in game and in the text that conveys what the setting and play might be like. I like finding the version that resonates with me and my specific friends.
However, lots of people like premade content. Lots of people like the more gimmicky (in my mind) seeming game bits, either as a fun thing ie to offer an alternative to other content, or things like board games that permanently change as you play.
I would guess Gloomhaven isn't for me, but is worthwhile for many folks.
So how is anyones play going? Whats seems great, what seemed really different that worked, or didn't?
