It seems, no matter what race I begin with (usually Terrans, Yor, or Ios are preferred), playing a Huge or Gigantic Star Field in Challenging Mode, I cannot keep up in population with the AI races (usually 5-7 competitors).
At first I thought I was getting bad planets or perhaps too far away from others, etc. But it seems after playing about 6 different starts over the past two weeks or so, I am always behind in Population after the first few months.
What am I doing wrong and how can I improve this?
