Historical Accuracy?

Cohorts were roughly about 420 men according to my now 6 feet under tutor (god rest his latin soul).

I did think about trying to replicate some of the military and political situations of ancient Rome (i.e. feeling my treasury run dry due to the expense of maintaining the Rhine legions in their forts), but it's actually not fun, since it's not possible to use the limited mechanics of an RTS game to reflect complex human societies and their development.
RTW is a historically-based game, not a historical simulation. This is what people seem to forget when they get upset about things like legionary armour being 1.86cm too narrow across the belly button or whatever.
Personally I love history, but I also like to enjoy myself by taking Roman armies to Denmark, conquering the world as Carthage, and using unit types which probably never existed.

I tend to make my Roman armies up to mimic historical roman legions. I use ten units of legionary cohorts to represent the main heavy infantry, one general, two units each of archer auxilia, auxilia and cavalry (usually legionary cavalry) and one unit of praetorians to act as a bodyguard for my general/final reserve in battle. I add two scorpions/repeating balistae when I can get them. Overall a fair reflection of a roman legion considering the restrictions of the game.
