I'm thinking they wanted to represent the different incarnations of Hellenic/Hellenistic civilization this time around. They've done Alexander for Greece in every other version of Civ. Civ5's iteration seemed especially Macedonian based on its features. Only Civ4 even had Pericles as a second option. I can appreciate their efforts to give us a more traditional Greece based on Athens and Sparta. Looks like they're releasing Alexander for those who still liked the more aggressive Macedonian play style from earlier versions of Civ. I'm withholding judgment for now in the hope that we also ultimately get the other more diverse civs we've been hoping for. We just need to make it clear what the fans want. If enough of us are demanding a certain civ, it should incentivize 2K to let Firaxis give it to us.
