Actually Byzantines called themselves Roman from the rise till the fall of their empire,while everybody else called them greek.The Byzantines called themselves Roman, until they got very weak in 1204 A.D. Then they started calling themselves Greek.
Whenever I play a scenario -mod with the Byzantines included I think they are always overpowered in an unrealistic way.Whereas their massive lands and technological superiority they had reflects on their game strenght,their neverending civil conflicts over the crown and their unmatched corruption cant do so.I dont know what could be done in order to avoid ruining balance,maybe a negative leader trait such as "corrupted".Baah too much
