Not that it's a very important question about a very important point of gameplay, and it didn't even ruined the game for me, but I was wondering, so, well, I just ask :

The Macedonian faction's symbol is an inverted V, while the Greek Cities faction has some kind of lightning bolt. What's disturbing me, is that Sparta is the capital of the Greek Cities faction, and the inverted V was the symbol of Sparta (the inverted V is the capital lambda, which stood for "Lacedemone", another name of Sparta ; it was on every spartan shield, and was the symbol of the city).

So, well, I'm wondering ^^
