Everyone should play through all of it! Eluna and the Moth is amazing! Sunswallower's Wake is amazing! A Walk in the Unlight is amazing! I may like this game just a little bit.
To everyone who never played it, Wildermyth is essentially a story focused, randomly generated fantasy X-COM. You play as a company of heroes crossing the wilderness and hunting down monsters, coming across all the fantastic things therein. Campaigns take in-game decades to finish, so the heroes you start with might retire and their kids might join the fight later on. It's one of those games where I have run out of people irl to recommend it to, so now it's your turn!
