Ok, so the last thread on this subject erupted into an only somewhat relevant flame war regarding human biodiversity and it's link to cultures both of the real and Civ variety. Since said thread is long buried and I'd rather start anew with none of the baggage the original carried, I have several proposals for this more modern C2C team's review. Firstly, the Progenitor Civ concept is, in my opinion, still a sound one, but it is one in need of revision given a closer casual look at the field of anthropology. Thus; This is by far the most pressing point; we will need a clear and coherent consensus from the C2C team members involved as to whether the cultures should be linked genetically or linguistically. Neither presently has a clear advantage in terms of game utility and practicality, and both would result in radically changed culture pathing (the Roman culture would become crucial for Medieval-era kingdoms, as it was historically, while Proto Indo Europeans remain a keystone in both plans). Next, Persia would either be an early branch of Proto Indo European (genetically) or Semitic (lingistically). Thirdly, I am unsure whether Aborigines and Polynesians should be progenitors of each other, or whether they should be seperate Progenitors, or whether they should respectively be tied to some Southeast Asian or Indian and Taiwanese or South American civilization. Lastly for now, ethnic and languages isolates will prove troublesome regardless of which route we take. The Japanese and Koreans are historically prominent and highly homogenous ethnic and linguistic groups, so they are likely to take center stage much more readily than more inaccessible cultures like Canada or Pakistan. Secondly, a new system for breakaway civs in Rev. There will be a list of names, assigned by several different regions (not the Culture (X) ones, as these are too broad to serve as singular categories for these purposes), namely: Aboriginal American (first the Confederacy, then the fifty states in declining order of population, so the Texas and California republics are most likely to form, perhaps with Deseret as a special dynamic civ name for a Mormon America) Arab (starting with the non-African Arab League nations, then moving down to historical tribes like the Ghassanids) Berber (the Maghreb nations) Canadian Celtic (including Ireland, Scotland and Wales) Central African Central Asian (including Mongols, Tibetans, Turks and Uyghurs) Chinese (all of the ethnic groups save the Tibetans and Uyghurs) Dutch (including Boer) East African East Coast Indian Eastern European English French German Greek Indian Italian Japanese Korean Latin American (including the Caribbean, save for Afro-Caribbean nations like Haiti and Jamaica) Mesoamerican (including the Southwest Indians) Plains Indian Polynesian Portuguese (including Brazil) Scandinavian (including Iceland) Siberian (including Ainu, First Nations and Inuit) Slavic Spanish (including Filipino Southern African South American (the natives, that is. Modern nations are covered under Latin American) Southeast Asian (including the ever mysterious Indonesia) West African (including West African diaspora nations like Haiti and Jamaica) West Indian (including the Plateau and Great Basin Indians, having nothing to do with Caribbean natives, who are covered under South American) The in game civs would all be assigned to some place under these categories. Whenever a Revolution or other event occured to split that civ apart, the program would first search for the "actual" civs placed in that list. So, for instance, if an Olmec player had a revolution, the program would first opt to have the revolutionaries be Mayans, then Aztecs, then a long series of names which don't currently have civs in their own right at the moment.
