I would love to see some improvements to my capitals. I think that a set number of planets modified by map size would be great. After so many planets I can upgrade my Civilization capital to more then just a colony capital. Added tourism Influence and science would all be candidates. I would also like to see regional capitals show up. Lets say at 10 planets I get a civilization capital on my home planet, then every 10 new planets I get to designate on of my colony's to upgrade to a regional capital. It just feels weird that my Civilization capital of 100 planets looks and acts like a back water colony capital. It would be like stoping into Novi's City hall and it being Washington DC (A Michigan, Detroit area reference as I live by Stardock's offices.)
