A hidden programmer message is hidden in the files of Disk 3, stating:

"great special thanx to you, ARIKO...from your husband, HIDEJI".

In the very first Japanese release of the game, at the bottom of the well in Corel Prison, a rare debug enemy known as "Test 0" that was accidentally left in the game on its initial release can be randomly encountered. This encounter does not require cheats or hacks to occur, although GameShark codes can be used to access every other debug enemy battle in the game. This battle was removed from all future releases of the game. "The Completely Unauthorized Final Fantasy VII Ultimate Guide" by Versus Books, released in 1997, features an entry on this enemy (note that the HP listing in the guide scan is incorrect; Type 0 has 30000 HP).

According to the game's art director Yūsuke Naora, he liked how his design of the city of Midgar turned out, having envisioned the city in his head as a pizza while he was designing it.

After the first AVALANCHE mission at the start of the game, Barret will reference this inspiration when talking to Cloud about the upper plate of Midgar:


Additionally, the name of the song "Underneath the Rotting Pizza", which prominently plays in many of the slum areas in Midgar, is a reference to its design.

According to character designer Tetsuya Nomura, Aerith's dress was specifically designed so that it used a low number of polygons. Cloud was originally designed with slicked-back hair for the same reason.

The original idea for the game had it set in modern New York City in the year 1999, and was intended to have a "detective story" theme, with a character called "Hot Blooded Detective Joe". The early script had him chasing the main characters, who would then blow up the city of Midgar.

One of the early art directions of the game was going to use 2D pixel-based graphics. There was one concept image early in the development featuring an isometric view in this style using Final Fantasy VI character designs, including Locke.

The last phase of the final boss fight pits Cloud in a one-on-one duel against Sephiroth, who will always go down in a single hit, regardless of whether Cloud attacks him or steals from him. This is facilitated by giving Sephiroth only 1 HP, which can be seen in-game with help from a GameShark code.

The number 7 is very prevalent in the game.

• AVALANCHE resides in Sector 7 of Midgar.
• Tifa's bar is called 7th Heaven.
• At the start of the game, seven people are either living or staying at the 7th Heaven -- Cloud, Barret, Tifa, Marlene, Biggs, Wedge, and Jessie.
• The books in the Shinra Mansion library shelves form the letters "VII".
• The red plane in Costa Del Sol harbor has "VII" painted on the side.
• The Gold Saucer has seven areas of attractions.
• The Ancient Forest has seven treasures.
• The Turtle's Paradise awards seven items for completing the flyer-hunt sidequest.
• Aeris and Ifalna were held captive by Hojo for seven years.
• It's been seven years since Cloud left Nibelheim to join SOLDIER.
• Tifa spends seven days unconscious before waking up after the Weapons awake.
• Red XIII tells the party that Meteor will reach the Planet in seven days.
• Cloud levels up to level 7 in the first battle.
• If a unit's HP hits 7,777 during battle they enter All Lucky 7s status.
• The "lucky" handicap reel on the Battle Square is called Lucky 7.
• Most characters have seven different Limit Breaks. The exceptions are Cait Sith, who has two but with various different outcomes, and Vincent, who has four, but each form has two special attacks. This makes for seven characters who have seven Limit Breaks.
• There are nine main playable characters, but only seven are mandatory.

There is a bit of unused dialogue found in the Final Fantasy VII game data that would have taken place outside the Shinra Headquarters, before the party head in for the first time, and in the elevator, if the player entered the building through the main entrance. Outside the building, Barret would suggest that Cloud knows the place well, to which Cloud would have answered it to be his first time there. Barret would then have said he has been at the headquarters before, back when he still had both his hands. The elevator scene is similar, with Cloud saying he's never been to the place before and asking if Barret is familiar with it, which would have prompted the same response from Barret. These bits were cut off the final game and nothing in the finished version suggests Barret would have ever visited the Shinra Headquarters before.

Barret was the first consistently dark-skinned playable character in the Final Fantasy series as Leo Cristophe from Final Fantasy VI was light-skinned in his sprite form.

Final Fantasy VII's original Spanish translation is considered to be one of the worst of all time, even being called the "Spanish Zero Wing" by some (the infamous "All Your Base are belong to us" videogame).

There are some minor mistakes, such as mistaking "Well" for "Rueda" (that means Wheel) or "Hurry" for "Hurra" (which means "Hooray") but there are others which completely destroy the dialogue. The most remarkable examples are:

-Every time that someone talks about Aerith, Yuffie, Tifa or any other female character from the game, they will be referred as if they were male, as some words in English ("the", "a", almost every adjective... etc.) are used for both males and females, but not in Spanish where most of them vary depending on the gender ("un/una", "el/la"...).

-The word "You" in English is both singular and plural, but in Spanish there are two words for that, "Tú" for singular, and "Vosotros" for plural. The word "Vosotros" is never used in the game.

-The word "Miss" is translated as "Merma" (literally "Decreases").

-One of the worst translated parts is the Gold Saucer, with sentences that don't make any sense, such as "Allévoy" (something like "Hericome" instead of "Allá voy", which means "Here I come") or "¿Quién participaré??" (literally "Who will I participate?").

-The word "Party" is used in every wrong way possible. Sometimes it says "Haz un partido de tres", which means "Make a political party of three", but the most known mistake is in Kalm's Inn, where the inn's owner says "Su fiesta le espera en el piso de arriba" ("fiesta" here meaning cheerful celebration).

According to the Final Fantasy VII Ultimania Omega, earlier drafts of the game's scenario involved three characters known as the '3 Saints'. Not much is known about their original role in the story, other than they were kidnapped by Sephiroth, and that Red XIII knew more about them than the rest of your party. The only Saint mentioned by name was called Gandalf, who was captured by Hojo and "practically crippled" in a Shinra laboratory.

Red XIII had a subplot that was cut from the game as the plot developed in a different direction. Originally there were to be two Red XIII clones created by Hojo called Cobalt XIV and Indigo XV. The player would have to fight all three of the "Red XIIIs" and figure out which was the real one, with the three swapping places periodically. Defeating the real Red XIII by accident meant the player had to fight the following boss battle with Hojo with only two party members. Cobalt and Indigo would return in the final dungeon of the game, turned into cyborgs and determined to prove they were superior to the real Red XIII.

There is a hidden "Red Man" in the Corel Prison. The model is hidden from view in normal gameplay. There are no other models like this in the game, and it is thought to be a signature from one of the designers.

In the early development stages, producer Tetsuya Nomura planned to have only three playable characters in the entire game. However, during a phone call with Yoshinori Kitase, they decided that one of the three characters should be permanently killed off. After the staff chose Aerith, Nomura created Tifa as another possible love interest for Cloud.

In an interview, Tetsuya Nomura stated that he envisioned Cloud and Sephiroth's relationship to be like that of Musashi Miyamoto and Sasaki Kojiro. This influenced not only their appearances, but also the appearances of their swords.

"For me, it’s of course Cloud and Sephiroth. My concept for Sephiroth from the beginning was that everything about him would be kakkoii. His battle movements, and all his in-game scenes too. My image of the relationship between Cloud AND Sephiroth was that of Musashi Miyamoto and Sasaki Kojiro, and I had them in mind when I designed their appearance, as well as their swords. Of course Cloud is Musashi, and Sephiroth is Kojiro."

One of the advertisements for the game reads "Someone please get the guys who make cartridge games a cigarette and a blindfold." and "Good thing, if it were available on cartridge, it'd retail for around $1,200." This was a jab at Nintendo and their cartridge-based platform the Nintendo 64.

During the Motorcycle Chase FMV, Midgar is incorrectly spelled Midgal on the side of the truck door. This is probably because the letters "R" and "L" are commonly mistranslated from Japanese to English.

Final Fantasy VII heavily references the Lurian Kabbalah [kah-ball-a]. Kabbalah is a Jewish school of thought that also refers to the mysticism of Judaism and Gnosticism, a collection of ancient religions. Not only does FFVII draw from the beliefs of these religions, but it incorporates what actually happened to the followers in real life, as well as using Hebrew in the formation of character names. A few examples are:

• The Gnostics were persecuted, like the Cetra.
• Sephiroth's name comes from the term Sefirot (meaning "counting" or "enumeration"), which refers to the ten aspects of God in the Tree of Life.
• The sixth sefira in Tree of Life is beauty, known in Hebrew as Tif'eret {ti-fah-ret}. It is possible that this is how Tifa's name was derived.

The meaning of "Safer Sephiroth", the name of the final boss -- not counting the unloseable battle that follows -- has been the subject of debate. Many assume that it's a mistranslation of "Seraph Sephiroth", as Sephiroth's form bears an explicit resemblance to the six-winged Seraph angels (particularly as depicted in the painting "Stigmatization of St. Francis" by Giotto).

However this is not true, as the Japanese name is romanized as Sēfa Sefirosu. The actual translation is 'Sepher', which is Hebrew for the word Book. Sephiroth's name itself is based on the Hebrew word Səphīrōth, which can be translated as Numbers. The name Sepher Sephiroth can thus be translated as "Book of Numbers", one of the books in the Hebrew Bible.
