I assume this was directed at me. In this case, I side with you, if only because I think in this case gameplay should trump flavor.
While it is true that Byzantines considered themselves they considered themselves to be Roman, the culture was significantly different, in ways that makes it pretty hard to say "Byzantines were Romans." Yes, they technically were, but I would call them Byzantines and end it at that, not to mention the aformentioned confusion in having two Roman Empires.
The suggestion might work if you made it conditionally so that the West must be dead, but otherwise Byzantine is perfectly fine.
I didn't mean to trash talk your country, by the way. Sorry for that.
no, I just kidding .. I would find more appropriate Hueland or Stupid Monkey land
