Quoting EternalRequiem, reply 17would be damn nice to have a fort type building to defend on the boarder of your ZOC which is smack dab next to another factions ZOC. Of course it's a special building that isn't part of a city therefore you have have a small army you've sent out build the building. This is nothing unusual because the Roman Legions would when they were deployed build forts when they dug in when invading or defending an area.
I'd love to see something like this. It's been brought up quite a bit and never gotten much dev traction. Upgradeable forts that require resources to build and maintain, but don't provide much besides some ZOC control, greater sight, and defensive bonuses. Can build them for border watch, in strategic places like passes, or have an ultimate "last stand" fort for your Sov to run to if you're getting your ass kicked a la Helm's Deep.
exactly, and believe it or not that doesn't come from me, that idea alone is actually from an older game...
FFH2 mod for Civ4 there's a nice little python code someone created that allows forts if you build them to update and upgrade if they are manned. You have a unit on top of said for and you can install a fort commander. What this does is make the fort active (if it was in the plot near a settlement it would be worked by the people in the settlement and alter become a castle and then a citadel.) The fort commander basically runs the fort and grants bonuses to units that are placed under it's command. This allows the fort to upgrade after a certain amount of turns and also projects a culturally zone, or in the case of EWOM, zone of control, besides obvious defense and light of sight bonuses.
