politics and society planet

Not sure what you're suggesting. I have two types of planets: 1- A Shipyard world that has resource facilites and 2- Minor planets with nothing but research facilities. I don't have your problem because my type 1 planets are building ships or other stuff and my type 2 planets produce only research points and don't require any micromanagement. Then I filter my production list to show only SY planets. Anything to make empire (micro-)management easier.

In the early days, after the release, I had considered adding in Planetary Projects, which would be one-per-planet, and have 0 size. It wasn't possible back then, since I couldn't limit how many could be built, but now I can.

Your idea is similar in mechanics to mine, and both can be achieved. I'm pretty sure you can make the events script add various facilities to planets.

For your idea, having different 'problem' facilities that cause negative effects, then providing corrective facilities that can be built, would let you do this. The events script would both add the problems randomly, and remove them from any planet where a corrective facility has been built.

I think this idea could be expanded to be more than a problem hunt, though, as that is micromanagement without any positive rewards. Say, being able to add these special facilities and improve some element of the planet.

A project a day keeps the deadline away.

I micromanage too much already. I'd hate to add to my workload. Of course, this is just a personal preference. I can see how others would like this.

Oh you mean somthing like...

The Event "Colony wants to declare independence from the Empire" occurs and you build "Lower taxes" as Project/Facility with 0-Space to prevent this event. So this Planet also requires the Facility "Local Parliament/Goverment" to gain access to and build "Lower taxes".

Did I get it right?

"Lower taxes" can have real effects such as no production and reduced resources to the empire. I'd prefer to use to use troops to stop any moves to independence.

As a defender or someone whose planet is now occupied by someone else, I'd like to see something at a social level that reduces the effectiveness of troops. Nothing wrong with making things difficult for the enemy.
