I read through these posts a few times but don't grab the idea. From what I understand it is a silly concept. More random stuff (will it turn into a city, will it flip?) means less strategic thought, which is what the game is suopposed to be all about. Ultraworld, what you want can perhaps to some extent be modded but please leave the original game alone - with all respect, but suggesting to do it the other way around sounds a bit arrogant to me. I understand you are Dutch. I looked up the word 'settler' in an English-Dutch dictionary and it translates as 'kolonist'. Like somebody said above, the idea of colonies as something different than settlements is a nice Firaxian idea.
