1. Do workers use up all of the money in the coffers on a daily basis or do they use up a little each day? The workers always use 10% of the total money in your coffers, up to a max of 75k (meaning you have 750k+ in your coffers). 2. Is it actually possible to make a huge profit by investing into the kingdom and using the resources to make more money and investing the recent profit? Yes, but it will take time due to the limited rate of resource gathering provided by the kingdom. 3. What resources do you think would be the most efficient money? 3b. What is the best use out of the resources that makes the most efficient money? Coal, maple and flax are possibly the best money makers. Each has it's own benefits, I guess it just depends on what you use you them for. Maples are only really good for selling. They'll typically run 80-100 each, 100 being quite rare nowadays. The biggest benefit of maples is the extra bird's nests you get and the possibility of good tree seeds. Flax is 100 each but I would recommend spinning it all and sell the bow strings for 200 each. Coal can be sold or smithed into whatever you want. I personally have never got coal but I've heard it's a great choice in MTK.
