I wanna first state that this is only an inquiry, but not some kind of bullshit appeal that it should be made
a realistic mod for the Barbarian invasion expansion.

In BI then many of the available units are exactly the same, or very generic. Perhaps all in all there are 2-3 special units for each faction,
excluding the Roman empire (Western and Eastern) and the Sassanids.

I am just wondering whether there are enough historical sources and evidences to make a Total war mod during the Migration period,
or the last days of the Western Roman empire.
Like the available units in comparison to EB.

Or is BI a one big cliché/fiction? in regard to all non-civilized factions...
