Probably a redundant question...

..but I'm not a modder myself and I can't find the answer. Is it possible to import a single civilization from one mod-mod to another? Specifically, I want to import the Palatinate civ from Orbis to FF. Is this possible? Thanks in advance.

Depends how the mods are organized.

Some mods are modular, and store their chvilization spells and such in different folders, which makes things a lot easier. Others are not, so you'll have to copy all the separate XML and python elements over.

The other thing to consider (If you haven't yet) is whether civilization mechanics will work across different mods. (Anything related to Orbis espionage, for example, won't work in base FfH).

Generally speaking, if you know XML and can at least look at python, you can do it.

The only real hurdle you'd face is the fact that the Orbis and FF techtree are radically different; Most things need to be shifted around in the civ.
