Final Fantasy XII is a role-playing video game developed and published by Square Enix. The twelfth main installment of the Final Fantasy series, it was first released for the PlayStation 2 in 2006. It introduced several innovations to the series: an open world; a seamless battle system; a controllable camera; a customizable "gambit" system, which lets the player control the artificial intelligence (AI) of characters in battle; a "license" system, which determines what abilities and equipment can be used by characters; and hunting side quests, which allows the player to find and defeat increasingly difficult monsters in the game's open world. Final Fantasy XII also includes elements from previous games in the series, such as Chocobos and Moogles. The game takes place in Ivalice, where the empires of Archadia and Rozarria are waging an endless war. Dalmasca, a small kingdom, is caught between the warring nations. When Dalmasca is annexed by Archadia, its princess, Ashe, creates a resistance movement. During the struggle, she meets Vaan, a young adventurer who dreams of becoming a sky pirate in command of an airship. They are quickly joined by a band of allies; together, they rally against the tyranny of the Archadian Empire. Final Fantasy XII was both a critical and commercial success, earning several Game of the Year awards and selling over six million copies on the PlayStation 2 by November 2009. In 2007, a sequel titled Final Fantasy XII: Revenant Wings was released for the Nintendo DS and, in that same year, an expanded version of Final Fantasy XII, titled Final Fantasy XII International Zodiac Job System, was released on the PlayStation 2 exclusively in Japan. A high-definition remaster of the International Zodiac Job System version, The Zodiac Age, was released worldwide for the PlayStation 4 in July 2017, for Windows in February 2018, and for the Nintendo Switch and Xbox One in April 2019.
