Roman civil war (?)

[Titus Marcellus Scato]

I guess the Rebel Romans would have to take the place of an existing faction that has already been wiped out. Epirus, maybe, or KH.

Don't forget, the family member bodyguard unit will need changing as well, otherwise you'll have Rebel Romans being led by Greek generals.

Then you get into the destroyed factions' building tree, that needs changing to Roman....along with their default AI 'personality', to make them act like Romans....

Quite a lot to do.

[Marcus Ulpius]

I think it would be possible to take out some faction (like Saba or Saka) - something far away. Then turn them into Romans and script the event when the civil war starts, and what provinces the rebels would get. I'm not familiar with the EB script, but I think scripted appearance of factions is possible. It looks though that the amount of work is quite large here.
