Pretty much. Dug out areas constructions of any type with varying values for anything and high values for all industrial activity and production units, walls and buildings. Wagons should not add to Civ value and with certain things such as mobile claims coming about actually detract from civilization as it declares them a more nomadic or warlike peoples (e.g. 'less civilized') where armaments of of armor and Flag bearing and Stronger beasts of armor, toughness and strength for the necessary function of either types of people. Whatever they roll out for warfare mechanics, I'm just extrapolating from what exists. I imagine that breeding for warfare could have to involve some work against breeding for production and even involve several animals to achieve various shit. These, in that quality levels might also contribute to Civ values.
This then that as Civ grows, more world becomes generated at some rate. In other words, Enforce scarcity to enforce development to a certain density and make new territory a thing that all contribute to and continually race towards and for pushing them out but keeping them closely established together from world generation. Making new players that arrive progressively further out from the point of origin of the world. This relationship equaling into a margin of expense versus interest in the abuse versus extortion/alliance

relationships with new colonies that see increasing pressure to band together for and against these powers at relationships that then further serve to make them forward that subservience as they gain power and development and push outward to create a social dynamic that arises not out of inability to do damage but out of economic efficiency that still sees violence necessary from time to time as player want to cash in on their investment of capability and don't give a shit about the economic returns because looting your rebel sub nations and then taking that plunder on your original core antagonist nations destroys civ values and could slow expansion creating world wars that everyone prepares for.
Also creates incentive to limit damage done when attacking/retaliating.
Well what is this that I can't see
With ice cold hands takin' hold of me
Well I am death, none can excel
