Sid Meier's Civilization VI is a turn-based strategy 4X video game developed by Firaxis Games, published by 2K Games, and distributed by Take-Two Interactive. The latest entry into the Civilization series, it was released on Microsoft Windows and macOS in October 2016, with later ports for Linux in February 2017, iOS in December 2017, Nintendo Switch in November 2018, and PlayStation 4 and Xbox One in November 2019.
Similar to previous installments, the goal for the player is to develop a civilization from an early settlement through many millennia to become a world power and achieve one of several victory conditions, such as through military domination, technological superiority, or cultural influence, over the other human and computer-controlled opponents. Players do this by exploring the world, founding new cities, building city improvements, deploying military troops to attack and defend from others, researching new technologies and cultural civics, and engaging in trade and negotiations with other world leaders.
The game featured several civilizations not featured in previous incarnations of Civilization, while many returning civilizations had new capitals or new leaders. A critical design focus was to avoid having the player follow a pre-set path of improvements towards their civilization which they had observed from earlier games. Civilization VI places more emphasis on the terrain by "unstacking" city districts from the main city tile and giving bonuses for placing districts near certain terrain types. Other new features include research on the game's technology tree based on nearby terrain, a similar technology tree for cultural improvements and a better government civics structure for those playing on a cultural victory path, and new artificial intelligence mechanics for computer-controlled opponents that include secret goals and randomized engagements to disrupt an otherwise stable game. The game's first major expansion, Civilization VI: Rise and Fall, was released in February 2018, a second expansion, Civilization VI: Gathering Storm, followed in February 2019 and a season pass, The New Frontier Pass, in May 2020.
