/me wonders what AC is....I just tried Civ3, hard to get used to the gameplay..
The units all take turns, and it looks like it was supposed to be designed for a board-game, once u get into it though its really cool...so I would probably vote Civ3

Novus Ordo Seclorum

Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.
