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.
