I really like the new tax system. Makes it harder to get the gold you need.
I don't like that none to low is a 40 point difference.
Imo, the rate should increment by 20 points each time: -20, 0, 20, 40, 60, 80, 100; coorisponding naming equivelants can be: charitable, relaxed, low, average, high, oppressive, tyrannical.
This approach would give the player a wide flexibility in how to tax citizens. Imo, the unrest should not be the only bonus/penalty associated with tax rate. Makes it too linear if it is. %chance for rebellions/free slave units and prestiege/heroes should also be incorporated into the system so that you can play off certain strategies.
