Isn't imperial Rome and the Romans before that almost the same?! The Parthians, I remember them from Parthian tactics in AoK Might be interesting. The Huns, hmm, not sure about them, how long did they last 50 years?! Not much info about them if I'm right. Only Attila, but then you have had most of it. The Dacians, never heard of. Maybe adding eastern civs to the game would be a nice adding.
