To overpopulate, first build something like four Academies. When you press [F11],
you will see the population. When you get up to 50 on multi-player, delete something.
Next, click on your Academy then click on the Phalanx or Hoplite about three to four
times. Do this on the second academy, then the third, and so on. This will trick the
CPU into thinking you have to have more, so you will have a bigger army. You can end
up getting 50 or more.
