Short answers, pulled from the story.
Final Fantasy V was released in Japan in December 1992 for the Super Famicom, where it sold roughly 900,000 copies on its first day. It did not reach North America until September 1999, as part of the PlayStation compilation Final Fantasy Anthology, nearly seven years after the original Japanese launch.
The Job System in Final Fantasy V lets players assign any of 22 jobs (26 in the Game Boy Advance version) to their characters and carry learned abilities across job classes. It was designed by Hiroyuki Ito and is widely regarded as the game's defining gameplay feature, praised by critics as one of the most in-depth systems in the Final Fantasy series.
Final Fantasy V sold approximately 2 million copies during its first two months in Japan and a total of 2.45 million units for the Super Famicom. The North American PlayStation version earned Greatest Hits status after selling more than 350,000 copies.
Nobuo Uematsu composed the Final Fantasy V soundtrack, which consists of 56 tracks. A two-disc album released alongside the game extended the total to 67 tracks. The track "Dear Friends" later became the title piece of the 2004 concert tour Dear Friends -Music from Final Fantasy-.
Final Fantasy V was directed by Hironobu Sakaguchi, the creator of the Final Fantasy series. Prior to the release of Final Fantasy IX, Sakaguchi named it his favorite Final Fantasy game.
Square abandoned at least four separate localization attempts between 1992 and 1999, citing the game's high difficulty and tone as barriers for Western players. Translator Ted Woolsey stated in a 1994 interview that the game was "just not accessible enough to the average gamer". The game finally reached North America in September 1999 as part of the Final Fantasy Anthology compilation.
