I had an idea for a mod, but I have no clue how hard it is to be done. I thought it might just be a xml fix, but that is why I am here. I guess in must be done in python, but I don't know.

I wanted to experiment with the idea of making something just like a city except it is not a city. I want to restrict buildings and units built in it and maintain cities at the same time. I was thinking of making military bases that would make borders like cities except it would not be culture related it would simply be military borders. It might look confusing on a map I know, but I wanted to experiment with it. So is there a way of just copying the city setup and renaming them from cities to bases?

Someone did something like this: a one-city challenge varient, where only your main city was a full-fledged city. Every other colony was effectively just a military base.

First of all thanks for reply. I thinking you are referring to "Capitals and Outposts". I was't really looking for just changing the properties of later cities. I am looking for any idea how to basically make a completely new set cities that have nothing to do with culture borders. The best why I guess I can explain is imagine running two civilizations on the same plot of land, but of course you control both groups of cities at the same time. I mean actually adding a line to the xml that units/buildings can be built in city and a line that units/buildings can be built in base.

I am horrible at explaining it, but thanks again for the reply.

That would be a hugh SDK/Python/XML job.

Thanks for the reply as well. Then it is probably way above my level. I was hoping I might find something simple to change in a xml file that could add another group of cities. I thought of making capitals and regional capitals this way as well. Oh well thanks anyway.
