I had a question regarding population growth. I was under the assumption that I had a pretty good grasp on how it works, but something had happened in the game I am playing now that I thought was odd. During the initial colonization phase, the first planet I colonised was a Class 12. It was the best one I could find. Other planets I colonised later were a Class 6, and the Class 4 that starts in your home system.
Throughout the growth of these planets, I found it odd that both the Class 4 and Class 6 were growing in population faster than the Class 12 planet, since they are of lower qualities, they both had lower approval rating, and they were both colonised after the Class 12. By the time the Class 6 had filled up to 6 billion, the Class 12 was between 4 and 5 billion. The Class 4 and 6 also never got morale buildings, they are both specialised to research, where the Class 12 did get morale buildings.
The only thing I can think of is maybe distance from the capital affects it? The Class 12 was way outside of my main influence area and was close to other civs planets, but it still maintained its own bubble of influence, and later flipped another civs planet in the same system, with the support of an influence starbase, and I built the Restaurant of Eternity or whatever its called on the Class 12 planet.
Its a moot point now because I am far enough in the game where most of my currently controlled planets are at max pop, but was curious if anyone had any insight as to why the Class 12 would have grown slower? There has to be something I was overlooking.
I am playing Dark Avatar, with a fresh gold edition install, no updates, can't get internet access for my laptop where I'm at at this time, but have EU coming to me in the mail.
Thank you for reading.
