Perhaps a class overhaul would be interesting. The main reason people play Commoners is that they have no bonuses or penalties, making them perfect for keeping things simple. Overhauling existing classes and creating a Nomad class for travelers, allowing them to sleep comfortably in the wild, whereas the Sedentary class would be forced to sleep in a decent house, could make things interesting.
It would also be necessary to find a way to build real makeshift shelters by mixing branches with leaves for example to be able to put a bed of hay inside and would only be able to put it inside. Travelers will therefore have to go through this step to sleep rather than stupidly putting their bed and sleeping anywhere.
Regarding food, the cellar concept is interesting in itself. But it's too easy to acquire at the beginning because there are no size requirements. The storage periods, or even the basic expiration dates, should clearly be reviewed. Because champions and vegetables have completely excessive storage periods, meaning that with a good stock of vegetables/mushrooms, you can easily last three years.Perhaps making grain/vegetable plants rarer in the wild and increasing the number of animals in the wild to encourage the player to use hunting more at the beginning of the game and farming later.
