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. A part of the Civilization series, it was released on Microsoft Windows and macOS in October 2016, with later ports for Linux in February 2017 and iOS in December 2017.
As with other games in the series, the goal for the player is to lead their fledgling civilization from an early settlement through many millennia to become a world power and achieve one of several victory conditions, such as through military power, technological superiority, diplomatic leadership, 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.
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 improvements from the main city space and giving bonuses for placing improvements near certain terrains. 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.
