In a distant future, scientists were able to build small alternate Earths. The scientists programmed each of these Worlds with an individual set of laws and rules which the residents strictly follow and consider most important for their lives. These may be exploration, consumption, economics, military, etc., and each is unique. You can visit all of these 504 alternate Earths to experience how the people are living, and decide which of these worlds harbors the best civilization. On which World do you want to live?
