Could the fact that you cannot place more than one unit in the same tile signify that the whole concept of the Civilization unit production is in for an overhaul?
It has been mentioned that you will be limited to how many units you are able to produce in relation to the quantity of relevant resource you have access to.
What might be the case is that instead of utilising 'production' to create a unit, one expends population points? For example, you gain access to Iron, you can now produce 5 Swordsmen. For every one Swordsman you produce you must expend a population point in the selected city.
Furthermore, it has been hinted that a unit does not necessarily get destroyed in battle if it is defeated in battle. What this could mean is that in most cases (unless the attacker is much more advanced than the defending unit) a defender is able to retreat and gain experience from every battle. And for that unit to heal you will have to expend more population points (or fractions thereof) for the unit to heal.
What this could encourage is the tactical use of available military units and viewing them more as an army, or a legion as opposed to a 'unit'. Perhaps as they become more experienced you must expend population for them to increase in size for example. Maybe as you advance technologically one Iron will enable you to produce double the amount of Swordsmen or whatever.
