I think it's better to make a decision at the start of the game but your idea could be work like the Governmental Legacy Bonuses or Pantheon in some way.
Depending on how you define 'start of the game' we're actually pretty close: I'd have the decision point come after you see your starting position, because the terrain and situation of that position should have a Big Effect on that decision, and even what decision can be made. I would also make the resulting decisions perhaps more 'wide ranging' than others would: I'd like to see a range of Starting Technologies instead of one (Agriculture) only. BUT if there ain't a domesticable animal in sight, Animal Husbandry is not a legitimate choice for a Starting Tech.
Did you forgot the Greece because they represent the Minoan Civilization with the city names
After blowing a year plus on a Classical Studies advanced degree program, I should hope not! While Crete had some of the rudiments of civilization, including one of the oldest stone paved roads known anywhere, the earliest elements of 'civilization' in relatively dense 'city' - type settlements and hieroglyphic-style writing don't show up until around 2000 BCE - 2000 years after the nominal Start of the Game. The Greeks didn't become recognizably 'Greek' until they
migrated into Greece some time after that: the 'Dorian' Invasions. In fact, I would argue that 'Minoan' Crete was not a Greek Civilization of any kind: they didn't share language or religion, there are indications of a very strong Matriarchal component to Cretan society absent in Greece, and even the Cretan Palace Architecture has more affinities with Asia Minor than anything on 'mainland' Greece - compare the floor plans of Cretan Knossus and Phaistos with Beyce Sultan in southwestern Turkey, and you'd swear the same architect initialed all three sets of plans!
After the Mycenean Greeks took over the island, of course, Crete was 'integrated' into the Greek World so that 500 or so years later when the
Iliad was being composed they are listed as part of the Greek contingents.
I means that every Civ must get age dependent Abilities. The problem is, not all Civs exist over all the time. What modern representation should the Mongols get if they rule the world?
That would depend on the Game Events and Decisions that got them there. Historically, one set of Mongols ruled China and became a Chinese Dynasty, another set became the Golden Horde stamping down the Russian city states - and could have wound up ruling central Russia, had they played their cards better - yet other groups morphed into the Timurids and Mughals, ruling large parts of Asia Minor and India, respectively. So I would argue that there are "Nine and Twenty Ways of constructing Tribal Lays, and each and every one of them is Right!" ( - and thanks for giving me a chance to quote Kipling, always a Plus).
What I would like to see in the game is a Chance to see what kind of Mongol Civilization I could build that could not only conquer the World (God Knows they came close enough to that historically) but also rule it for any length of time - see the Yuan, Golden Horde, Timurids and Mughals above, all temporary, all long-gone, for examples of how they failed to maintain initial conquests.
What frustrates me as much as anything in the game is that I start 6000+ years ago with a civilization with certain Inalienable Attributes which have little or no bearing on where I start from and with what resources, and WHICH NEVER CHANGE no matter what happens, either to them or by them. It produces, for me, extremely One Dimensional games. It also produces extremely One Dimensional Civilizations, which is why we have to argue about Multiple Leaders to try to introduce some of the variety that any civilization develops the longer it hangs around, and why the Mod Files are full of 'alternative' Civilizations to those in the game, because Historically, almost any civilization that lasts more than a couple of hundred years changes, mutates, and morphs into something different, and the game now simply doesn't allow for that.
