Editing the default Empires

[bratacsga]

For instance, if I give the UNE the Mechanist origin for one run, will I have to manually put them back to normal for subsequent runs or will my game save multiple variants?

When you save them they create a copy with your changes. As far as I know the game does not ever modify the files where the premade factions are stored. It will just save the edited version in the file with your custom factions.

Ah, cool :) Thanks

you can overload the def by making a copy that uses their same unique start, and making it 'force include'

it will only include one empire that uses a specific start.
