In simple terms, micro is all the small things you will do. Like moving your units, attacking specific units, Moving your farmers so they are closer to a specific building to increase food output, etc. So yes, the small things in life. Adversely Macro is basically grand strategy, technology, buildings etc. Anyway. If we're going to have a morale system, i would like it to be a very subtle thing. It should be modeled by group situation, not individual situation. So if they are mortally wounded, they won't care, but if all their friends die? Example: you have 100 units in formation, only, say, 20 will actually live long enough to surrender, if they are freshly trained. 15 veterans, 10 elites, and 5 champions. Math that out how you will, but i think that would be best. But it would naturally be more complicated, Elephants were used to maximum effect as a scaring tool, not a fighting tool. Most men are willing to fight a fair fight, but be crushed underfoot by a big beast? Not cool.
