GSC Gameworld of Cossacks and American Conquest fame are doing the tie-in game. Given that the game is using the Cosssacks II engine it should be worth looking at. JFK was a travesty of history but was entertaining. Alexander could get the history right - though classicists advising a movie did little for Gladiator as not even an inscription in excreble Latin was altered - or it may not, but it will be very entertaining.
