Yeah - just invade a planet as rebel with this setting:

 

        Empire, BasicEmpire

        Pirates, None

        Rebel, BasicEmpire

 

Excelent to create a balanceing verify session. I wonder if we can do that at a galactic level too ?! ???

The better question is if we can add more factions like that 

He he, it works at galactic level, but why use BasicEmpire, the rebel AI works, see my mod. The empire AI will try to get a research lab to advance, the rebel AI will use droids.
