Inamong the first strategic choices to consider is which Legacy Path to pursue from the start of the Antiquity Age. Each Legacy Path has unique challenges divided into milestones.
Completing these milestones awards Legacy Points spent at the beginning of the next Age. These paths are divided into four categories — Cultural, Scientific, Military, and Economic — each with its own particular requirements based on a historically relevant idea or concept.
Completing a Legacy Path awards a Golden Age bonus while failing to complete any milestones in a path unlocks a Dark Age option.
In the Antiquity Age, the four Legacy Paths in are relatively straightforward but challenging for the uninitiated. While it's possible to pursue all four Legacy Paths simultaneously, doing so might fail to complete any in their entirety due to the Age Progression meter.
Each milestone that every leader in the game reaches advances the Age progression by a certain number of points, so there is somewhat of a limit to how many milestones and bonuses can be acquired.
