As far as we have seen we will be to build a building at every 10 pops and keep stacking them with all buildings give full values. This mean that for example if you have a city with 100 pop you can build 10 buildings. If you build 10 training camps with each training camp give +20% Manpower, this city will produce 200% additional Manpower and the more buildings you can build the more extreme the values can become.
Granaries for example may let a city grow to arbitary size as the +10% growth from granaries counter the -10% growth from the 10 pops needing to support it which make it rather easy to support massive slave population to mass produce goods such as gems.
Maybe there should be some sort of diminishing return, like the first training camp give +20% Manpower and at some Point an additional training camp may increase Manpower by only +5%.
