Update is out.

The ancient greeks, however, did distinguish these two peoples as separate ethnic groups

The illyrians and Thracians are peoples that have a lot in common, so you could say that this is exactly what I have in mind

...I did make Dacia, @Chrabaszcz6.

Did you mean Thracians?

Could you create a civilization of the Etruscans? Or maybe the Germans with Arminius? Or Illyrians or Dacians? Have you ever thought about something like that? I have several ideas written down for these civilizations, including leaders and unique units, and I'd be happy to share them.The civilizations I mentioned are not randomly chosen; no one has made them yet, and for example, they were playable in civ5 or other games.

All your latest creations have been super interesting and this one is no exception. Look forward to trying it out one day.

This was one of the strangest and most convoluted civilizations I have made so far.
