Sandbox features: Economy

Hey there,

I was thinking to present you on Patreon, features that I am going to implement in-game for the free-roaming.
First will be the economy and I will show you a bit the concept that I had in mind.

The engine will be based on income and outcome for the kingdom. 

Formula:

Income – Outcome = kingdom economy

Income:

City citizen income + land taxes = Kingdom income

1) City taxes (citizen taxes):

Formula:

The number of citizens in the city  x  base tax per citizen = city citizen income

The base tax per citizen is set by the player in the Economy screen where the player will be able to input a value. It will have a default value of 5 coins.

At the default value of 5, it will not have an impact on citizens' happiness (to be posted).

Taxes and happiness (only for the city):

Lowering the taxes will have a positive impact on the citizens. The logic would be: 4 coins = +1 happiness; 3 coins = +5 happiness; 2 coins + 10 happiness; 1 or 0 = +15 happiness.

Increasing the taxes would decrease happiness with the same values from above.

 2) Land taxes from nobles.

Nobles pay a fixed income for their establishments. Either if we are talking about estates or villages (each village/estate is own by a noble/boyar.)

Villages will generate a revenue of 500 per week.

Estates are going to generate a revenue of 250 per week.

Expenses:

Army:

UPDATE: 15.07.2020

Total army strength = SUM of all the strength generated by the army units.

Each army unit will have a value as referenced for strength as it has for costs. Strength will be used when battles will be fought. So, for example, the enemy army will have a total strength of 2000 and for the player to trigger the victory, he/she will require an army of strength >2000 

Colonia’s soldiers = The standard soldier of Colonia 

Costs = 2.5 bronze coins per week/ per unit

Strength = 1 x number of units

Mercenaries = Hired soldier that will fight for Colonia.

Costs = 2.5 bronze coins per week/ per unit

Strength = 2 x number of units.

Special units = These are units that will be available for the player to recruit after passing milestones in the story. Example of units: Native units (local units before the colonization), Legion of Doom (units unlocked after converting to a certain deity), etc.

Values are set per soldier. Ex: For 5000 Colonia soldiers that means 5000 X 2.5 = 12,500 (which are deduced, every week from the kingdom’s treasury).

*Soldiers/mercs are not added to the population cap, nor do they pay taxes. *

UPDATE: 23.07.2020

Empires tribute:

Being a vassal under the empire requires a certain amount of coin to be deducted from the treasury, to be sent to the empire at the end of each week. 

The default amount at the beginning will be 500 coins.

This is will be a variable on which the player will not have direct control over it. It may be influenced by the outcome of the story (to increase or decrease.)
