Building Military Units in the Classical Era

i was playing as axom in the mediaeval era, or maybe that's ha classical era. The big thing is that building military units takes populationy wich is very good because of that. You can't just span the largest army in existence. You you have to pay attention to slowly building that army,. making sure you have food support and not just building up industry constantly. This tends to put the breakes just becoming the giant super power. i managed to get a game where i was pretty this is on, youknow, the civilization difficulty level.
