One of the unique mechanics that differentiates Civilization 7 from previous entries in the franchise is the Age mechanic. This mechanic makes play sessions much more engaging and gives the player smaller milestones to aim towards in the form of Legacy Paths. There are three Ages in the game, and each age comes with four Legacy Paths that the player can pursue.
In the Antiquity Age, players can choose the Culture, Military, Science, or Economic Legacy Path, each of which grants the player special bonuses that can be implemented in the next Age when completed. The Science Legacy Path is called the Great Library Legacy Path, and requires the player to obtain a certain number of Codices to complete.

Rewards for Completing the Great Library Legacy Path in Civilization 7
There are three milestones for each Legacy Path in the game. These milestones serve as a way for the player to get rewards even if they don’t finish the entire path. Each milestone gives the player Legacy Points and a Legacy, both of which become relevant when the next Age starts. If the player doesn’t complete any milestones at all, they get a Dark Age Legacy, a powerful boon that comes with a caveat. If the player completes the full Legacy Path, they unlock a Golden Age. In each Age, only one Golden Age and a Dark Age can be selected.
