Ideally autonomies would split some fleet point into a separate pool and allow them to do everything other factions already do - wage war, send disruption fleets, colonize.
Hmm, that's an idea. I'll experiment with this when I get back to working on Nex; hopefully not making it too good for player (free invasions and new colonies) won't require too much messing with the values involved.
(My mental concept of autonomous colonies was more like what autonomous regions are like on present-day Earth; different autonomous colonies of a single country don't have any particular reason to cooperate with each other as a unified entity any more than they do with the central government, and invading someone is more foreign policy than they're usually allowed to have)
Hi!
I'm glad to hear that. When I talked about vassalisation, I imagined something like this. So basically if you choose so, you create a vassal and afterward when they cn act like any other NPC, except they can be controlled to a degree by you. Basically, that's a choice: you choose not to care that much about them, so they generate less revenue, but at the same time they can defend themselves, create defense fleets, invasion fleets, etc.
Maybe the player could have some say in any invasion, like when you have to click a button to accept a peace offer.
Also if the vassals could improve their planets, that would be nice, too.
Great mod, keep up the good work!
