I was wondering if there are any plans to implement similar reforms for other factions? I was thinking maybe the "uncivilised" factions could have a mechanism for turning a tribal confederation into a centralised kingdom, and the hellenic ones could maybe establish hellenic colonies in new areas, enabling them to further integrate them into their empire. For example: If the Ptolemaioi could give land grants in central Egypt to Galatians and have them fight as heavy infantry, what is to keep them from doing it in other regions? It may be counter-factual, but so is Hayasdan establishing a new Persian empire.
