I am playing MA Man in CBM and follow the advice to maximize money.
I have Order 3 Growth 3 Sloth 1 Heat 1 Misfortune 1.
I try to have a Forrester patrol each province with a halfway decent income, and overtax them to 110%
Seems to work great. But how could I really maximize the gains? Where is the break even between killed population and more income?
Any experience?
