To expand upon what ozz said we feel its a little off-putting to name all the units in their final Greek in the previews, so you'll see them in their proper forms ingame but here we'll keep it simple. For instance the Illyrian Archers would actually be toxotai and cavalry would be Illyrioi hippeis, bodyguard cavalry are Illyrioi Somatophylakes and elite heavy spearmen Illyrioi epilektoi logchophoroi. I think we'll also include an optional back to english patch which will help the player who feels a little overwhelmed by all the greek unit names to understand a little better. However in all these games you learn a little something so who knows, perhaps by playing you'll learn a little ancient greek.
