The in-game economy is developed on a value-based design rather than quantity based. This helps to control the inflation of the resources and overpricing of any recourse compared to other resources. This is achieved through implementing a mix of a set of constant values and a set of variable values.
The constant values include the manpower requirement for each action, the durability consumed, the cost of manpower, the cost of site upgrade etc.
The variable values include the energy consumed, manpower health consumed, the resource requirement for repair etc.
