But that’s the flip-side of this suggestion – by adding weekends, the devs would be able to reduce the amount of time Hearthlings spend socializing and relaxing during weekdays, since the weekends (and possibly festivals) would make up for it.
I think the hearthlings actually have a lot of time available for relaxation already, but I view that as a good thing. Stonehearth isn’t, say, Caesar or Anno, where everything takes place in a bustling metropolis. It’s mostly set in a frontier town, and a relatively quiet one at that, at least for a good chunk of the gameplay. If you grow your town into a bustling metropolis, cool, but the core game is built around a smaller scale; and one which discourages that sense of urgency. It’s a chill, laid-back and cutesy game, so it doesn’t make sense to have the hearthlings running around frantically for the whole time. Sometimes, sure, they should be more active; but I think that being able to give your hearthlings plenty of leisure time is a marker of success in Stonehearth.
