Real world Balance
I honestly couldn't think of another way of putting it in the title.
What I'm talking about, is that common, rock-paper-scissors approach to balance in which Armor A, is countered by weapon A, which is defeated by armor C, ect.
IE: Archers are defeated by Cavalry, who are weak to spearmen, who are weak to archers.
How much of this will there be? Will you have cavalry units, who are especially effective to certain units, and other units especially effective against those?
To add on to that further, with the Unit editor I read, that was possibely being released with the game itself, how far could one edit units in that in terms of the above mentioned subject. IE could one make a cavalry unit, that was light and fast, with light armor, especially good against ranged units, but horrible in fighting against most anything else?
