* ActorAllusion: Cid, a MadScientist obsessed with a strange, godlike being, is very similar to [[WesternAnimation/AeonFlux another character portrayed by John Rafter Lee]].
* ExecutiveMeddling: Why Vaan and Penelo exist--the original protagonist was going to be Basch, but the developers were concerned that an older hero wouldn't go over well with Japanese audiences, since [=JRPGs=] usually have younger, {{Bishonen}} heroes. They become proper characters in their own right in the {{Gaiden Game}}s. This trope, combined with tightening the loose ends that come with six years of DevelopmentHell is why the International version of the game is markedly different from the original game.
* TroubledProduction: ''XII'' has the rockiest development of any ''FF'' game to date, thanks to the collapse of Squaresoft (courtesy of ''Anime/FinalFantasyTheSpiritsWithin'') and its merger with Enix, creative differences with series creator Hironobu Sakaguchi (who resigned and was replaced by Akitoshi Kawazu), and the rough equivalent of $35,000,000 US spent to make the game happen. Five years is a preposterously long time considering how Square had been producing main series ''FF'' games at a steady clip of every two years. To put it in perspective, ''VideoGame/FinalFantasyX'' was released in 2001, the first year of the [=PS2=]'s life cycle, whilst the much-promised ''XII'' was released in the run-up to the [=PS3=]'s launch and (At least outside of Japan) ''after'' the announcements of ''VideoGame/FinalFantasyXIII'' & ''VideoGame/FinalFantasyXV'' (Then ''Versus XIII''). In fact, ''Final Fantasy XV'' is the only game in the series to have been in development for longer than ''XII'', at ten years & counting as of 2016.
** Halfway though production, Matsuno resigned from Square Enix, citing health reasons. He had lost much of his leverage after his project, ''Spirits Within'' collapsed like a bad soufflé, and Square Enix wanted to go [[HollywoodOld in a more youth-oriented direction with the game's characters]]. Considering how much bullion they sunk into the game, you can't blame them for being a bit cagey.
* WhatCouldHaveBeen:
** Original design documents and concept art showed that the main protagonist and player character was supposed to be Basch... wearing full armor and a thick, bushy beard.
** In addition to Revenant Wings, the game was supposed to have another sequel allegedly titled Fortress. The developers making Fortress went bankrupt, but a few remnants of it survived, such as some concept art, combat storyboarding, and [[http://www.youtube.com/watch?v=kq6XiYQFBgA one amazing track.]]
* WriterRevolt: The developers were pretty open about how Vaan was [[ExecutiveMeddling forced as the main character by the higher ups.]] In the final game, while Vaan starts out as the default playable character, he spends most of the time standing in the background in majority of the cut-scenes and is mostly inconsequential to the overall plot.
** Somewhat VindicatedByHistory as Vaan became popular enough in his native Japan to be the game's representative in the Versus series and later, Final Fantasy Explorers.
