This is mostly for late game play for efficiency reasons, and assumes that there won’t be a functional change (new production recipe, etc).
- Market Level 3 - This could do well just adding 2 more worker slots, but storage capacity and spoiling rate improvements could be considered. When you have upgraded all your houses to Mansions, you have a lot of non-grocers leaving their work to stock their shelters, due to Grocers not being able to keep up.
-Tannery, Cobbler, Soap Shop, Basket Weavers - These could be upgraded simply to allow more workers in the same single building space. This avoids inefficiency in the late game. Other buildings can remain as is to avoid making things too easy.
- Apiary - Creating sufficient honey to supply for Beer, Medicine, and Pastries in the later game means having to have Apiaries out in random empty spaces, and Farmers are already a bit funny when your Fields are spread out around the map. An Apiary upgrade which gets an exponential increase in Honey production (not Wax) based on Honey Bonus would really help with that.
(Say the upgrade is barely worth it unless it’s going over the bonus of a Field, for balance purposes)
