The phrase identifies a specific category within tabletop gaming. It denotes expansive strategy games simulating the development of societies across extended periods. These games typically involve numerous players, complex rulesets, and significant time commitments, often several hours or even multiple sessions to complete a single play.
The appeal of this type of game lies in its immersive simulation of historical processes and the opportunity for strategic decision-making on a grand scale. Players manage resources, develop technologies, engage in diplomacy or warfare, and navigate the challenges inherent in societal growth. The extended play time allows for dynamic narratives to emerge and fosters intense player interaction.
