Factory Economy
This mod tackles the overproduction that is caused by military factories and naval dockyards in late games. When you’ve conquered half of the world and left with 1000 military factories, not using them feels like a waste.
Consider your Civilian Factories as an abstraction for buying power, the more you have the more you can afford to build military/naval equipment etc.
Penalties will only apply, and appear, after 100 Military Factories or 40 Naval Dockyards are in use, you can check this from the decisions menu. This means you could have 300 factories but 100 only producing military equipment, therefor penalties won’t apply.
For Example : After war time, you can focus on rebuilding your nation by limiting your military production.
It should be expensive to maintain and produce for a large military complex, so you will have to find a balance between producing equipment and building new buildings/infrastructure etc.
