Should there be a population Limit?
If not, then a player can make as many units as they want (and fill up the map - which is obviously silly and not desirable).
Maybe a level should have a population limit. Smaller maps = fewer units, but also helps levels be more distinct. One level on X map you are destitute and on the verge of collapsing as an army (near the beginning of the game) and so can't make more than 20 units or whatever, but you come back later in the game with the resources (not in game, but like story resources) to have a bigger army.
