I see, there was a thread about "Strategos" sub mod, and there is Alex sub mod, so, I though about EB sub mod, but with the time frame of 3-rd century imperial crisis, where Roman Empire is divided between several rival usurpers, each of those wishing to become an emperor and unite the Empire. On the other hand, the empire is attacked by various barbarian factions and by Persians from the east. I don't know what was the situation at the eastern part of the EB map at that time, but, I'm sure something was going on there as well. I don't know if mod like this exists, but I think it could be an interesting idea for a sub mod.
