I was creating a custom map and I placed a Civilization Capital on my home world. When I started the game, there were 2 capital buildings on the planet. The usual colony capital and a fancy Civilization capital. Has there always been a difference between the two? All I have ever found on my home world is the normal colony capital. The bottom right of the screen displays the words "civilization capital." Has there always been a special Civ capital building? Do we research it down the line? Anyone?
