In my current ERE campaign on M/M, the Huns have done well by taking Mediolanum, Ravenna, and Rome ad have a fairly nice little homeland. It is around 395 A. D. and their one large army just left Rome to rack up the needed number of province for the win, I guess. Problem for them is that I have a large Army/Fleet ammaseed across the Adriatic in preparation for my final campaign to capture Rome. I don't really know much about the other Barbarian faction or what they are doing.
