The Age of Enlightenment expansion for Rivals of Catan introduces three distinct gameplay eras, each with unique challenges. In the Era of Explorers, players navigate hazardous waters, interact with islanders, and recover shipwrecks while completing missions. The Era of Sages focuses on strategic resource management, requiring players to prevent famines and defend their territories. The Age of Prosperity shifts to cultural development, where players construct schools and civic buildings while managing potential unrest.
