Was it possible to make more confusing sentence? On topic: kingdom is profitable if you can spend 75k every day, meaning you should always have more than 750k in kingdom. I usually keep 1.5-2.2 mils and visit kingdom twice a week to keep my approval rating close to 100%, once a week i collect my resources. I have it 100% on flax and 50 on maples (because of bird nests and tree seeds). Flax is most i think one of the most profitable commodities, and if you spin yourself to BS then you can sell it very fast with insane profit. Of course all this possible only with Royal Trouble completed.
