This kinda reminds me of a rather unpleasant arguement I was in before Civ IV was released about ZoC. Anyway, in said arguement I recommended giving a fort a culture bonus, so it is kinda ZoCish kinda colonyish (the loss of colonies in Civ IV is one of the things that I lament the most). Anyway, is there anyway to make it so forts have culture around them, like a city? They would start at 15 culture (so they cast a culture area 1 tile in each direction), and have no way of producing more culture.
Better idea:
Keep forts like you had them for this mod. Add new unit: the Military Engineer. Acts like settler, but founds "Military Base." Bases are a cross between cities and colonies, and aren't as expensive or time consuming to manage. It would work like this: The engineer would move to the tile you want the base on, like one would with a settler. The founding of the base consumes the engineer. The base is a "city" that has a max culture level of one (for reasons I listed above). It would have no science, culture, or great person production. It would have no population. It would have hammer production that is either 1/2 the production of the highest city in your empire or the average of all (I can't decide which), but only military units and military buildings can be produced.
This idea seems to make sense to me, both historically and strategically, but I am afraid it would be too hard to write in to the game. I'm not good with codes and DOS-like programming (I need my GUI!!), but it was hard enough to explain it in this post; I imagine it would be infinately worse trying to explain it to the computer. I don't know, what does everybody else think?
EDIT: Wow, I never realized how old this thread is. Well, I still might get a response (fingers crossed).
