Macedon was given to us because there was a good portion of the community that complained that Alexander was leading Greece every time and should lead his own civ of Macedon instead. Now the devs decided the people were right, but that didn't mean they were going to get rid of him and most people still complain about it, except me. Honestly if it were up to me and we had to get rid of Macedon I would give up Gorgo as well and make Alexander the second Greek leader and he would still give it a more militaristic side like she does. In short there are really only two Greek Civs in my opinion which is obviously Greece (which only has two leaders) and Macedon. I agree that Egypt in the game doesn't feel like they are portraying anything Greek at all even if Cleopatra had Greek ancestry. If anything the only references to other Civs are to Rome and possibly even England (Shakespeare) in her quotes. As for the Byzantines, I'm all for them becoming their own Civ with their own uniques. However I also was thinking of a way for them to be put in the game without leaving another fan favorite out because we are obviously going to get at least 3 to 4 new civs in an expansion. As for unique units, no matter how they get in I would like for them to get a Dromon UU. I've wanted some sort of greek fire animation for them. I definitely would rather that than the Cataphract which indeed were originally Iranian in origin. The Varangian Guard would be interesting too but I could only see that if Basil II became leader as his UU.
