In an ancient world forgotten by time; enormous titans terrorize the land. Five tribes have been fleeing from the titans for centuries; but things are about to change. Growing city-states pledge to end the reign of terror; determined to take on the titans and make the world a safer place for all. Each city-state competes to attract the tribes; eager for the strength of the combined peoples; who are now leaving behind old traditions with the hope that the titans can be defeated once and for all.
In The Ancient World; players compete to grow the largest and most influential city-state by managing citizens; treasury; and military and by defeating titans. Players take turns sending citizens to take special actions or using military cards to attack titans. One of the actions a citizen can perform is to build Empire cards; which give more citizens; money; and abilities.
A city-state's influence in the world is measured by sets of tribe banners that it owns. Each Empire card has one or more tribe banners; and tribe banners can also be gained by defeating titans. Players gain victory points (VPs) for sets of tribe banners. After six rounds; the player with the most VPs from sets of tribe banners wins.
