It's hard to fathom all of the work it must take to make a massive role-playing game with a huge world, dozens of hours of content, and a story that is as long as about seven feature-length films. Even with teams of hundreds of people including QA testers and the like, it's impossible to catch every typo, continuity error, bug, glitch, or other type of mistake in games of such an epic scope.

Multiply the work of just one RPG by 30 or so, and it's no wonder that the entire Final Fantasy franchise (include spin-offs) has had its fair share of mistakes. In the early days, many of them were the result of translation mix-ups as there was often only one or two people tasked with translating entire games. But even since that aspect of it has become less of an issue, mistakes of all kinds persist in FF games, sometimes only being noticed by the hardcore, obsessive fans who play each game over and over again, front to back, and top to bottom.

While this list focuses primarily on the mainline FF series--meaning the numbered FF games through FFXV—we also wanted to touch on a few of the spin-offs as well since those have become just as important to the fabric of the FF legacy as the "core" games have. And while we feel there aren't a ton of spoilers here, especially for the newer installments, we still advise you to proceed at your own risk as far as that goes.

This Translation Are Bad (FFVII)

The PlayStation era was when game translations started to turn a corner and get a lot better overall, but that isn't to say that things weren't still pretty rough those first few years. For as much text as FFVII had, the translation was good for the most part, but a few pretty glaring mistakes still slipped through.

The first big one was the infamous "This guy are sick," spoken by Aerith when she encounters the guy in the tunnel in the Midgar slums. And poor Jenova has her only line in the entire game plagued with the misspelling "Beacause..."

What's In His Mouth? (FFX)

Some of the most charming moments in FFX come from the scenes where Tidus is basically teaching the sheltered Yuna to loosen up and be more of a normal person—well, except for the whole laughing scene. Yuna should ignore his advice on that one.

In the scene where Tidus is teaching Yuna to whistle, the voice actor playing him clearly already has his fingers in his mouth for a line or two before Tidus is shown putting his fingers in his mouth.

Free Turns For Everyone (FFIV Advance)

FFIV was when the Active Time Battle—ATB for short—system was first introduced into the series, in which battle turns are determined by a ticking down meter rather than giving players unlimited time to make a move.

In the Game Boy Advance remake of FFIV, a glitch led to both players and enemies given extra turns for no apparent reason. When a player gets an extra turn, nobody is complaining... but when an enemy gets one, a glitch suddenly feels much less harmless.

Ragnarok And A Hard Place (FFVIII)

Airships have long been a staple of the FF series, generally coming at a later point in the story when the game has determined that the player should finally get access to the entire map and travel to places that were previously impossible to reach.

But in FFVIII, if you're not careful with where you land airship Ragnarok, something else becomes impossible to reach—the inside of the ship. Landing it too close to a building or other structure can cause it to get stuck and not let you board it, forcing you to reload your last save to continue.

The Sketchy Sketch (FFVI)

While it's understandable that glitches and bugs can be missed when they are triggered by a specific and obtuse series of events or actions that would've been almost impossible for QA testers to have thought to try, sometimes there are really big issues that are much less forgivable to have missed.

Relm's Sketch ability in FFVI is so bug-ridden and unwieldy in the SNES original that most players just don't risk using it at all. Among the many glitches that can come from using the ability include effects as serious as having your entire save file become corrupted!

Look At Tifa's Eyes For Once (FFVII)

If there is any character in the history of the FF franchise that probably has to most often redirect the male gaze to her eyes from other parts of her anatomy, it is FFVII's Tifa. To that end, there's a good chance that some of you with less self-control probably never bothered to notice that she actually has red eyes. Well, sometimes she does.

Despite her having red eyes in her original appearance and written as such in her bio, in various appearances in other games her eyes are sometimes mistakenly colored brown without explanation.

Goddess Of What Now? (FFXIII Trilogy)

After its disappointing first entry, FFXIII ended up redeeming itself by becoming its own trilogy and getting much better with its second and third installments. By the end, protagonist Lightning proved herself to be among the upper echelon of FF leads. Still, there are some sloppy continuity issues between the three games in this sub-series of the franchise.

One of the more noteworthy errors comes by way of the character Etro, who in FFXIII-2 is described as the Goddess of Time, yet in Lighting Returns she has inexplicably become the Goddess of Death. Stay in your lane, girl.

Cid Is A Liar (FFIII DS)

Given the 16 year span between its original 1990 Famicom release and the 2006 DS remake, Final Fantasy III took the longest of any game in the series to be localized in English, finally bringing every mainline FF game to the rest of the world.

With this in mind, the game's story and script had plenty of time to be polished to an impeccable shine—which makes this glaring oversight that much less forgivable. When Cid tells the original story of the four children, it is full of inconsistencies with game's overall mythology that should've been caught in editing.

The Invisible Woman Of Cornelia (FFI)

Perhaps one of the most successful Hail Marys in history was Final Fantasy, a last ditch effort so save a then-fledgling company that ended up spawning a franchise that would live on for decades. Had FFI flopped, Squaresoft might have disappeared...just like an NPC in Cornelia.

There is a room in Cornelia that appears empty, but walking to the middle of it and pressing the action button results in a conversation with a seemingly invisible person. Originally referred to as the "Invisible Man of Cornelia," it was later discovered to actually be a female NPC behind this infamous glitch.

Any...Day...Now... (FF Tactics)

The Final Fantasy franchise has had way more spin-offs than mainline games at this point, but perhaps the most beloved of them all is strategy title Final Fantasy Tactics first released for PS1.

To be fair, FFT has a fair amount of little glitches and bugs, as is par for the course for such a complex game--but one stands out for how ridiculous and inexplicable it is. During a specific cutscene, when the text scroll gets to the phrase "little money," the speed at which the words are typed out slows to an excruciating crawl. And nobody... really... knows... why... it... happens...
