Hello.

It would be nice to add ship maintenance costs to the game. This would help alleviate the game's bloated economy. You can't spend more than half your income on fleet maintenance(we don't need riots on the planets, do we?), but there's a small caveat. Maintenance of large ships is not trivial, so they will be subject to an additional tax. Let's move from words to action. Let's look at a concrete example. Let's say our economy looks like this:

total_credit_per_sec = 100

total_metal_per_sec = 50

total_crystal_per_sec = 25

total_credit = 60000

total_metal = 30000

total_crystal = 15000

credit_per_sec = total_credit_per_sec / 2     # 50

metal_per_sec = total_metal_per_sec / 2     # 25

crystal_per_sec = total_crystal_per_sec / 2  # 12.5

max_fleet_supply = 2000

one_fleet_supply_cost_credit = credit_per_sec / max_fleet_supply     # 50 / 2000 = 0.025

one_fleet_supply_cost_metal = metal_per_sec / max_fleet_supply     # 25 / 2000 = 0.0125

one_fleet_supply_cost_crystal = crystal_per_sec / max_fleet_supply  # 12.5 / 2000 = 0.00625

frigate_supply_points = 4

frigate_maintenance_cost_per_second_credit = one_fleet_supply_cost_credit * frigate_supply_points # 0.1

frigate_maintenance_cost_per_second_metal = one_fleet_supply_cost_metal * frigate_supply_points # 0.05

frigate_maintenance_cost_per_second_crystal= one_fleet_supply_cost_crystal * frigate_supply_points # 0.025

additional_tax_capital_ship = 1

additional_tax_command_ship = 2

additional_tax_titan = 3

capital_ship_supply_points = 50

capital_ship_maintenance_cost_per_second_credit = one_fleet_supply_cost_credit * capital_ship_supply_points + ( additional_tax_capital_ship * credit_per_sec ) / 100  # 1.25 + 0.5 = 1.75

capital_ship_maintenance_cost_per_second_metal = one_fleet_supply_cost_metal * capital_ship_supply_points + ( additional_tax_capital_ship * metal_per_sec ) / 100  # 0.625 + 0.25 = 0.875

capital_ship_maintenance_cost_per_second_crystal= one_fleet_supply_cost_crystal * capital_ship_supply_points + ( additional_tax_capital_ship * crystal_per_sec ) / 100  # 0.3125 + 0.125 = 0.4375

Additional taxation for large ships is necessary to encourage players to build a balanced fleet. Therefore, the maintenance cost of a fleet consisting only of small ships will never exceed 50%. But a fleet consisting exclusively of large ships (40 capital ships) will cost much more. Let's say the cost of maintaining ships exceeds half of your income. Revolts break out on planets. The percentage of loyal population gradually declines, and income decreases accordingly. You can even increase the cost of maintaining large ships. The economy may even go into the red, and you won't be able to buy anything. This is the price you pay for a large, unbalanced fleet. Ultimately, the game becomes more realistic.
