The new changes to system generation are exciting to say the least. Moving the version to 2.0 is an intimidating prospect, I'll venture to say...
I did have one thought regarding the changing colony costs, which is the interaction with civilian shipping. Presently, civilian ships will tote colonists to any colony set as a destination which has some room. They sometimes overfill a bit but generally they get this about right. However with the new planet eccentricity, say I colonize Mars and place some infrastructure while it is closer to the sun, CC=2.11, and the civilians decide to fill it up with colonists. When mars orbits "away" and the CC rises to 2.5ish, those colonists will suddenly be too much for the life support.
So will civilian logic be changed to work on the body maximum CC in this case? Or maybe it already does and I don't know that because I never put colonists on comets?
