I like using tactics instead of just massing an army, and if you do it right you can beat a much larger force that the opponent has mustered with yours, if you are decent at managing your troops. Basically, the ability to mass armies of the size and scope of starcraft went away at exactly the moment that the game went 3d due to computational and engine limits. I don't think they are coming back, and I am pretty happy about it. Tactics rock, and if you don't know how to win without a humongous army to control you may want to read Sun Tzu's Art of War.
