Notes

MORALE

Improves fighting ability of your soldiers. Decreases by defeats or taxes, increases by victories or by religion.

TAX

You can set up taxes. Higher tax is, more morale you will lose by turn.

10g tax = - 0 morale per turn
20g tax = - 3 morale per turn
45g tax = - 7 morale per turn
75g tax = - 10 morale per turn

FARMS

Pretty much primary way to get income. You can build as many farms as you want.
Price of one farm is 15g and gives 5g income.

RULER, HEIR, DYNASTY, MARRIAGE

All player will start playing with their ruler but without any heir. To get heir, you will have to make royal marriage with other player / AI country.
Chance to get heir is random but with each royal marriage it is higher. You can have max 2 royal marriages at the same time.

If your ruler dies without heir and you have royal marriages, war for control of your throne will begin between countries you have marriage with. If you dont have any marriages and your ruler dies, then one of two things can happen;
50 morale or more - You will be able to pick any noble and make him king (or whatever else)
49 morale or less - Rebellion and war for control of throne
