Winning the game means being the player with the most Fame points when the last Era is won. You earn Fame in a wide variety of ways, including being the first or best at building Wonders, researching technologies, winning Battles, making Gold, and growing your population and your city. You also gain Fame for being a high-ranked member of a Civilization that wins an Era victory. With many options to gain Fame, the preferred strategy for doing so is a personal choice -- there are many ways to win Civ World! View the Civ World wiki pages on Fame and Eras for more information.
