What are the race\culture mixes like for each of the Colony powers?
Was wondering as i've noticed some of the Colonies seem to be quite distinct in this regard (eg. Mars = Russian).
When I came up with the original idea, I didn't consider, or even care, about racial mixes. Culturally, at this point they are Martians, Lunies, Jovians, etc.
Mars was intended to be more socialist as they had to ration supplies amongst a great many people in order to survive. The Lunies had a stronger sense of independence, despite still being dependent on Earth. The Kuipers are rough and ready survivaliests.
