First of all, I would like to express my gratitude for your work. This is a truly awesome mod.
However, during the course of my numerous playthroughs, I had realized the game misses one mechanic, that I think absolutely necessary for 4X games.
I think the game needs some kind of vassalisation mechanic.
I think currently the autonomous colonies are next to useless. They generate next to nothing and they are defenseless without player protection. They can't improve themselves without player intervention. Usually, I think it's more useful to give them away if you are over the admin cap.
But what about adding a new option? What if when we establish a new colony we could create a vassal faction?
This faction, while subservient to us could improve its planets, add new buildings, etc.
Every time we create, purchase, give away, or conquer a new market, we could give it to our vassal.
This would be a nice addition because this way our vassal would have the power of several markets, could improve itself, and could defend itself or help the player in wars.
I know it's a lot of work, but this would make much more sense compared to the autonomous markets, who are powerless, requiring constant babysitting and player intervention, and so on. I know that these vassal markets might be suboptimal when it comes to building new industries etc, but I think it's not really a big deal since autonomous markets are next to irrelevant revenue-wise.
