Can we construct multiple of the same building? Per manpower of maintenance, at the moment foresters lodges are just better than smithies. Of course two foresters lodges has a bigger upfront manpower investment but it is worth considering. Maybe some buildings should have a cap on how many we can build based on our size or other projects undertaken? e.g. Dredging the harbour or something might allow more docks to be built?
Docks also seem *incredibly good*. Holy monies batman Manaan. Building docks and lumberyards, along with a granary, shrines, and a farm or two seem like a winning bet to get us started. In the long term foresters lodges are arguably more efficient than lumberyards depending on how much you value money. Each forester lodge has a ratio of 8:1 on mats per manpower, while lumberyards have a 10:1 ratio. Lumberyards also have a -0.5:1 ratio on money to manpower p/wk whilst foresters lodges have a 2:1 money to manpower ratio.
Docks still make a crazy 40:1 money to manpower ratio so nothing much compares to the sheer economic value of BOAT.
EDIT: They also have a 30:1 food to manpower ratio compared to a 10:1 food to manpower ratio for our farms. This does seem a tad busted, if nothing else. Foresters lodges also seem a little overtuned, or else smithies and lumberyards are a little undertuned. Smithies in particular. At the moment docks are a do everything building, which I assume you don't want.
In terms of suggestions: the simplest would be up the manpower cost of docks to at least 0.25. That brings it line with the percentages most other buildings are also using. I really like it's identity as "The money building" but I understand wanting to represent fishing potential as well. Maybe there could be an upgrade or add-on to decide which element a given "docks" building is focusing on, or else two different buildings with different focuses?
