context: The game brought to the series many elements that were later used in subsequent parts of Final Fantasy and other role-playing games. Especially noteworthy is the new combat system called Active Time Battle, which combines the classic turn-based mode with the speed of the characters and the reaction of the player. For the first time in the series, Final Fantasy IV supplies each game hero with its own background and a predefined class. With a thoughtful plot, the latest technologies for its time, and a successful soundtrack of authorship, Final Fantasy IV was a turning point in the history of the development of the series and the RPG genre as a whole. Worldwide sales of various versions of the game have more than four million copies. In the 2008 year for mobile phones and in 2009 for Wii, a sequel was released entitled Final Fantasy IV: The After Years. In 2012, a re-release of the game for iOS was released, and in 2013 for Android.
