What types of installations do you put in systems when you first colonize them? Stuff like mines, listening posts, PDFs, etc.
I try to make it so the AI can take over development as soon as possible because I hate managing planets. I wish there was a system where when you order ships and the planet doesn't have enough resources to fulfill it the game will automatically makes a civilian contract to pick up resources from the closest source available. I also hope your civilians will be able to develop your planets more or less independently once you initially colonize them in C#.
