I'm assuming that technically speaking, there aren't any incompatibilities with mods that add new civilizations (I assume this because the "Mods compatible with VP" doesn't seem to have a blanket ban on mods that add new civs. But mechanically speaking, how do modded civs compare to the modded "vanilla" choices? Are they vastly over or under-powered in comparison? If it depends from mod to mod, the one that I like to include is Rhodesia. I also play with JFD's Switzerland, but according to the sticky it seems like JFD's civs tend to work just fine.
