I think those are too much. And you must take into account core areas and spawning zones from different civs can never intersect each other. Is it safe to assume we're all OK with the following core civs (grouped by cultural group, sorta): Egypt Babylon, Assyria, Hittites Hebrews/Jews, Phoenicians, Carthago Persians Athens, Sparta, Macedonia, Rome Those are 12 civs, having in mind they endured at least for some time and it would make sense for them to respawn (even if with other name) later. So the map must give plenty of land for all of them. I think with kravixon's WBsave and the proposals in this thread that is assured. Now, about the others. Sumer, Akkad, Phrygeans, Urartu: very shortlived; I'd only have the first one and never allow it to respawn. Chaldea, Elam, Juddah, Lydia, Medea, Seleucids, Parthia...: those aren't just entities by themselves; I know they were different than others but they can surely be merged with the core ones. Another greek one, Syracusae, Pergamum...: as I said, I see a problem having Sparta, Athens and Macedonia in Greece. None of them is supposed to colonize the Mediterranean. Athens, if we strecht it, only a little. So I propose an Asia Minor-coastal one. You can dinamically call it Lydia, Pergamum, or whatever. Early Barbarians: I just liked how celts were portrayed in RFC. Don't think they should appear, just because they're not supposed to be civilized the same way as the other civs. Separate tech tree? Forbidden workers? Dunno. Just don't like them enough. They're already controllable with scripted events. In any case, no gauls, britons, etc. Just celts. Germanic tribes: those could be in the very late game, but I still prefer the RFC approach for all barbarians and "natives". In that respect, I don't think the game should end at 476. Seems too late for me. Could be 200 AD or something like that. Another thing to consider: although Rhye implemented the dynamic civ names and change of personalities, I think it could be interesting to dinamically change a civ when it respawns, changing its name, leader AND UHV and unique power, depending of the current period. And making them accesible from the start scenario window. Know what I mean?
