From my very, very brief reading on the subject, I would look up discussions of the historical accuracy of the battles (particularly the more ancient ones). It seems that in real life, battles would typically take _much_ longer (an entire day), with breaks, small skirmishes, etc. The idea that each unit could be directed in coordinated, rapid, precise, and decisive movement with one unit throwing itself wholesale into the other and either obiterating or being obliterated does not really reflect reality.
I hate to give such an uninformed perspective on here (where expertise is valued so highly), and I hope people will correct me if I am wrong. But skepticism, assuming it's not blind and unchangeable but to ensure accuracy, is usually a good thing.
Still some fantastic games, though. Wonderful, very satisfying and engaging tactical strategy.
