Well, getting back on topic. I've taken a stab at selectively combining the suggestions so far, sorted them by period/region and into "necessary" and "less important", and used Wikipedia to get dates. Rather than just "filling up" as before I've tried to pay attention to having cities for each civ to deal with, more than one of that civ is otherwise isolated, and where possible placing independents between two or more civs.
There are way more than 25, so it might have to be pared down. I say might, because I'd like to suggest that a lot more independent cities would be a good for representing the way most Empires were built by conquest and not colonisation, and how minor states constantly rise and fall alongside the major civilizations.
Assumptions:
- There will only be one start, 3000 BC or thereabouts.
- Using the short chronology for the Near East.
- The Greek civ, like in RFC, won't make coastal colonies in the west, so these are independent. Anyway this has an historical basis: they weren't deliberate 'colonial' foundations, but date to a much earlier period, and actually appeared about the same time as the
polis back in Greece. They were culturally associated with Greece proper, but not politically subordinate to it. Same with the Phoenician colonies, but since there isn't a Phoenician civ that doesn't matter.
- Germany will be like it is in RFC: just one civ, representing the HRE inc. Austria and then modern Germany (although personally I think this is a great opportunity to represent Germany/the HRE better).
- Colonisation by missing civs (Spain, Portugal, Netherlands), will be handled some other way.
- The Songhai civ will be used to represent the Empire of Mali too, otherwise maybe there is a case for having Malinese cities e.g. Timbuktu as independents before they spawn.
- Siam will cover most of SE Asia.
- The Indian civ will mainly represent northern Indian civilizations and Empires.
