FFIV meaning in General ?

Final Fantasy IV, known as Final Fantasy II for its initial North American release, is a role-playing video game developed and published by Square (now Square Enix) for the Super Nintendo Entertainment System. Released in 1991, it is the fourth main installment of the Final Fantasy series. The game's story follows Cecil, a dark knight, as he tries to prevent the sorcerer Golbez from seizing powerful crystals and destroying the world. He is joined on this quest by a frequently changing group of allies. Final Fantasy IV introduced innovations that became staples of the Final Fantasy series and role-playing games in general. Its "Active Time Battle" system was used in five subsequent Final Fantasy games, and unlike prior games in the series, IV gave each character their own unchangeable character class.

Final Fantasy IV has been ported to several other platforms with varying differences. An enhanced remake, also called Final Fantasy IV, with 3D graphics was released for the Nintendo DS in 2007 and 2008. The game was re-titled Final Fantasy II during its initial release outside Japan as the original Final Fantasy II and Final Fantasy III had not been released outside Japan at the time. All later localizations of Final Fantasy IV, which began to appear after Final Fantasy VII (released worldwide under that title), used the original title.

The various incarnations of the game have sold more than four million copies worldwide. A sequel, Final Fantasy IV: The After Years, was released for Japanese mobile phones in 2008, and worldwide via the Wii Shop Channel on June 1, 2009. In 2011, both Final Fantasy IV and The After Years were released for the PlayStation Portable as part of the compilation Final Fantasy IV: The Complete Collection, which also included a new game, set between the two; Final Fantasy IV: Interlude. Ports of the Nintendo DS remake were released for iOS in 2012, for Android in 2013 and for Windows in 2014.

Retrospectively, Final Fantasy IV is often regarded as one of the greatest video games of all time, noting that it pioneered many now common console role-playing game features, including the concept of dramatic storytelling in an RPG. It has been included in various lists of the best games of all time, by IGN (at #9 in 2003) as the highest-ranking RPG, as well as Famitsu in 2006 reader poll among the best games ever made It also appeared in various rankings for Best Games of All Time for Electronic Gaming Monthly in 2001 and 2006, Game Informer in 2001 and 2009, GameSpot in 2005, and GameFAQs in 2005, 2009 and 2014.
