Encyclopedia of War: Ancient Battles

This game is actually a lot like chess! It’s a games designed to simulate
pitched battles in the Ancient world. There is a set of armies available from
the earliest times until the fall of the Western Roman Empire, in 475 A.D.

You can design the terrain and/or units, set-up each side’s troops and then
it’s just on to the battle. You are doing nothing but fighting the battle you
created.

There are also some pre-designed scenarios and maps for your enjoyment.
