I finally got around to getting this game and am playing a game on easy and trying to figure out how everything works.
The only thing I haven't been able to figure out so far it this:
I'm playing Humans. On Earth I have built improvements on all the available tiles. I cannot end the turn without picking something to be built on Earth. The only thing in the production queue I'm even able to build is another starship production facility. I haven't unlocked several of the items under the "projects" tab. So am I just stuck with building new starship production facility until I unlock the other options?
And is there an advantage to having multiple starports around a single planet?
