100% what i want is just the 3 buildings that give unity without perks. The Symbol of Unity, Autochthon Monument, and the Paradise Dome. It would be silly if I have to build these on every planet and then uncheck 'Redevelopment' just to ensure I'm not getting shorted on what I see as the second most important resource in the game. Research as a whole being the most important. And I agree with the Sector Systems part, but I had 9/14 when I started my mass expansion and added 12 Planets in one mass colonization and then 13 in one war and 13 more in another war. I would rather not have to wait until 5 pops to put a planet in a sector if possible.
