I agree with magnum, I want to see a fair amount of realism, but not at the expense of gameplay. if the game was completely realistic, the roman faction system wouldnt exist, and the other factions wouldnt be powerful at all, as each of them were strong at different points in time. Troop selection for the non romans would be pretty vanilla too. Doubt the germans would have sreaming women!

a 100% historically accurate game would be pretty predictable and boring, as there would be no randomness. All you need to do is have a history book open to know what happens next.
