Most of the Constructibles can be instantly finished with a one-time cost of Money or Population, an action known as Buyout. The cost of an buyout is primarly based on the industry cost of the item to be bought out. The Buyout action must always complete the item, it is not possible to use them to speed up without finish an item.
Researching the Masonry Technology will unlock the ability to buyout with Population; researching Encyclopedia will then lock out this ability.
Money Buyout[]
The amount of Money for buyout is always subjected to inflation; the more turns have passed, the more costly the buyout cost will be.
This inflation is a constant value, making it particular expensive to buyout cheap or nearly finished items as the game turn number progress.
Item Buyout Cost = IndP + Turn*(Turn/50)R
Ind = Remaining Industry of the item
Turn = Turn number
P = 1.18
R =1.55
Population Buyout[]
Unlike Money, when using Population for rush buyout Constructibles, every Population always equal to the same amount of Industry, based on the output of individual Worker in this city.
Any industry leftover from population buyout will overflow to the next item in queue.
Industry per killed Population = Worker Output*5
per always start as +6 per .
This value can be further increased via Workplace Family Infrastructures and Emblematic Quarters in the city, as well as Legacy Traits.
