This is the second major expansion for Civilization V, requiring the base game to play on PC, Mac, and Linux. It substantially deepens the late-game by introducing International Trade routes, the World Congress for global resolutions, and mandatory Ideologies for your citizens. The focus shifts heavily toward Culture, driven by Great Works, which now contribute to a Tourism victory condition. It adds nine new civilizations, eight wonders, two scenarios, and numerous units, significantly enhancing replayability and diplomatic complexity.
This expansion introduces several major mechanics that reshape how civilizations interact on the world stage. The most prominent addition is the system of International Trade, allowing players to establish trade routes between cities, both their own and those of other civilizations, generating crucial resources like gold, food, and production.
A key feature is the establishment of the World Congress, a global diplomatic body where civilizations can propose and vote on international resolutions. These resolutions can affect global rules, resource distribution, and even the standing of certain civilizations. Furthermore, as your empire develops, you must choose an Ideology (such as Order, Freedom, or Autocracy) for your citizens. This choice impacts your empire's happiness, production, and diplomatic standing with other nations that have adopted different worldviews.
The focus on culture is significantly enhanced through the introduction of Great Works. These unique items, created by Great Artists, Writers, and Musicians, generate Tourism, which is now a critical victory condition. Tourism directly influences the cultural pressure exerted on other civilizations, potentially leading to cultural domination if enough pressure is built up.
The package is substantial, offering significant replayability through new additions across the board:
As an expansion, this content is not a standalone title; it requires the base game to function. Its scope is considered significant, fundamentally altering the late-game strategy and adding layers of complexity to diplomacy and culture that were less pronounced in the original release. It provides expanded variety in achieving victory, ensuring that military might is not the only viable path to global supremacy.
This content is available on Linux, PC (Microsoft Windows), and Mac platforms.
