What I actually said was that I prefer to build econ. Though I did mention that building econ. requires turtling I am not afraid to go out and fight.
Leading a real army and leading a virtual army are actually very similar. The tactics are almost the same on all RTS's and thats what I use. Many of the great generals have created tactics for real combat, real combat tactics can be utilized for simulations.
Take, for example, chess. It was originally created as a way to predict what the enemy was going to do and how to counter that. Granted chess is much more limited than an actual battle and it only simulates field battles, but the same principles apply.
