Another Pacifist said:
If the argument holds that HRE-->Germany, then why not Rome-->France or Rome-->Spain, since the latter two are Latin cultures too?
By the same token, then why not HRE-->the Netherlands, HRE-->Austria, or even HRE-->Bohemia? The answer is that we needn't go down the slippery slope, whereby (almost) anything goes. Rome-->Italy makes more sense than Rome-->France, for two reasons: firstly, because France is already represented in the game, whereas Italy is not. And secondly, because Italy is not just any "Latin culture", but it's Rome's closest successor. So yes, in a way, France may be regarded as a successor of Rome, but not quite as close as Italy itself.
Or for that matter why not Aztec-->Mexico or Inca-->Peru?
Indeed, in my custom version of the mod, Aztecs get the dynamic names "Mexico" when running universal suffrage. Ironically, that's not so unhistorical as it might seem. The other day I've been to the British Museum's fascinating new exhibition about Montezuma (
http://www.britishmuseum.org/whats_on/future_exhibitions/moctezuma.aspx). The exhibition's posters begin by explaining that we shouldn't call the Aztecs "Aztecs" at all. Apparently that name was introduced in the early 19th century, and the correct name is Mexica. So if the Aztecs were still around today they'd be probably called Mexicans!
What IS constant is the ethnicity of the people that you're governing, and even that is fluid (what we call China today comprises of 56 official ethnic groups). To be accurate, the game Civilization should be called Ethnicity.
Are you suggesting that what identifies RFC-civilizations throughout the millennia is not so much cultural continuity, but some kind of genetic blueprint? If so, I disagree. I don't think DNA is the constant factor here. Indeed, there need be no constancy at all. Instead, we have a chain of influences whereby certain cultures influence their successor cultures. I take RFC-"Civilizations" to represent (very loosely and abstractly) these culture-chains. Four observations:
1) Although there has to be some similarity between a culture and its immediate predecessor, there may be little or no similarity between any given culture and its distant ancestors. What matters for the culture's survival is the continuity of the chain (e.g. at any point in the chain there should be at least one close enough successor), and continuity need not imply constancy.
2) Cultures, especially the more influential ones, may have more than one close successor. In that case the closest successor is the only continuator in the chain.
3) Culture A and culture B belong to the same "civilization" just in case there is a unique culture chain that goes from A to B. If A has no close enough successor, or if it has many equally close successors (unlikely), then there is no such chain.
4) What determines the closest successor is based on cultural influences, geographical proximity, shared traditions, language similarities, and other direct causal links. Those are all vague criteria, but that's ok. Civilizations are themselves vague concepts. What counts as the closest successor by loose similarity standards, may not be a successor at all by more strict similarity standards. I believe that in RFC the standard should be set very low, so that even modern Mexico may be seen as a successor of the Aztecs.
