Im doing a large-scale strategy game where you build cities and train armies from those cities (think toal war meets mega-lo-mania). I want a gameplay element like "army population" or "unit support" similar to those given from supply depots in starcraft or farms in warcraft. But i already have farms as a type of resource income. What would make sense?
I was thinking something like "barracks" each supporting 3 regiments of soldiers in the field, but barracks are very accociated with the actual creation of units in games (and i need that gameplay element as well since i need to train soldiers in some building in my cities).
Maybe cottages/houses to support units in the field? Could that make sence? What other ideas could you come up with?
