In MMO both micro and macro.
With your economy you can control each of your peasants, cows e.t.c individually (well battalinos of 5), setting these peasants on that tree, these to kill this cow e.t.c, this make sense early game, and even later on for players who like to fine-tune their economy. Or you can macro control - but either selecting your peasants or main economy buildings, and choosing what resources your economy should concentrate on.
Same with combat. You can only fight small scale battles if you choose (by keeping your armies small), or only large scale - by grouping your armies together into couple of 500+ unit armies. Since auto-match system finds opponents of equal strength.
