In the 11/92 issue of Famicom Tsuushin interview with game's composer Nobuo Uematsu, he was asked why he wrote the Black chocobo theme "Mambo de Chocobo" as a mambo song. He responded:
"Well, it was a samba (Samba de Chocobo) in FFIV. Originally I was imagining the Balinese kecak music for the chocobos. I sampled it over and over, but just couldn’t bring out that same kecak atmosphere. After that I had the idea of using a human vocal sample, and the mambo just fit. I’m not sure where the original idea for it came from though."
According to director/writer Hironobu Sakaguchi and writer Yoshinori Kitase, Final Fantasy V marked the first time they worked together on a game. Kitase then commented about their working relationship during the game's development:
"Mr. Sakaguchi and I worked on [the game's] events in a relay, so when we would go to work, the first thing we'd do is check the data the other had put up to check the continuity. We'd see each other's work and think 'I'll make something even better!' in a sort of competition."

The game contains two unused and unfinished commands, most likely used for debug purposes.
"!Dummy01" allows the user to target themselves, but then does nothing.
"!Dummy02" enchants weapons in the same way as the "magic sword" fire spell.

• Big Boss (which uses the same graphics as the Nut Eater)
• Chimera
• Mellusion
• Neo Goblin

In an interview, Hironobu Sakaguchi alludes to Gilgamesh's early life. Gilgamesh grew up in a village where all men were warriors. The Genji equipment sets were ancient and precious sets of armor from that village, and were usually passed on to its best warriors when they proved their worth in battle. It is said that the centuries of "blood, sweat and dust" accumulated on the Genji equipment have made them extremely resistant.
According to the "Chocobo's FF Laboratory" feature published in V Jump in 1993, Faris Scherwiz/Spoiler:Sarisa Tycoon from Final Fantasy V was originally a female gambler named Eva Scherwil. The developers encountered difficulties in making her fit in the game's world and atmosphere, and changed her into a pirate. In a later issue of V Jump, the developers noted Setzer in Final Fantasy 6 evolved from this early Eva concept.

Exdeath's original Japanese name is (エクスデス ekusudesu) or Exodus. This is worth noting as it would appear that Exdeath made appearances prior to Dissidia. In Final Fantasy XII, there is an esper called Exodus both in the English and Japanese versions that seems to resemble the knight form of Exdeath. In Final Fantasy Tactics Advance, a Totema called Exodus resembles Exdeath's tree form.

Exdeath's tree form resembles the treasured Yggdrasil of Norse mythology, which is often referred to as the beam that supports the universe.
The reason the original Final Fantasy V was never released internationally was because, as translator Ted Woolsey stated in a 1994 interview, "it's just not accessible enough to the average gamer". Plans were made to release the game in 1995 as Final Fantasy Extreme, targeting it at "the more experienced gamers who loved the complex character building". For unknown reasons, however, Final Fantasy Extreme never materialized.
