* BadExportForYou: A mild case of it in the European version of ''Blazing Sword'', as followed:
** The epilogue with Roy and Lilina as children and Zephiel turning out to be a bad guy was excised, for whatever reason.
** The level-up animation also reverted to how it looked in ''The Binding Blade''[[note]]The words just popping up out of nowhere instead of appearing in a flash of light[[/note]], likewise without any apparent reason whatsoever.
** Also, when you start the game with the English language, the opening text of Chapter 16x/17x has one line written in ''[[MindScrew Italian]]''.
* MarthDebutedInSmashBros: Actually, in contrast to the trope namer, [[AvertedTrope Roy did]] debut in that series, six weeks before ''The Binding Blade'' came out.
* NamesTheSame: Morgan from ''The Binding Blade''. We apologize in advance for having you find out that [[VideoGame/FireEmblemAwakening your son/daughter]] is associated with such a throwaway boss.
* NoExportForYou: Most Western players know ''The Binding Blade'' through a fan-created translation patch, as the game has never been officially localized. Its prequel averts this by being the first localized installment in the series.
* WhatCouldHaveBeen:
** ''The Binding Blade'':
*** Guinivere was intended to be playable and act as a second lord.
*** Tate and Lilina may have been related.
*** Zephiel and Murdock may have been brothers.
*** Zephiel's weapon, Eckesachs, had durability and was intended to be acquired after defeating him. In addition, the eponymous weapon was also intended to be acquired the same way.
*** [[spoiler:Jahn]] survived his battle and would be fought alongside [[spoiler:Idenn]] as a DualBoss.
*** Data exists that suggests that Blizzard might have been intended to have been a long-ranged weaponry. Evidently, Meteor was also supposed to make a return but was not coded into the game.
*** There may have been Dark Dragons fought alongside [[spoiler:Idenn]]. Complete with droppable Dragonstones that Fae would have been able to equip. The jury's still out on if they were supposed to be mass-produced versions of the stronger version of the Earth Dragons seen in [[VideoGame/FireEmblemAkaneia the Archanea games]], however.
*** An even earlier plan (revealed in the "Making of Fire Emblem" book) had [[AwesomeMomentOfCrowning Roy becoming king of the Western Isles]] halfway through the game. Which would explain why the Western Isles arc feels the least integrated into the overall plot in the final game: It was originally meant to be a "find a new land" plot.
** ''Blazing Sword'':
*** [[http://www.youtube.com/watch?v=8_ZZJYgqyhY Durandal]] had a different animation and appearance, and was intended to be used by Lyn, too.
*** Vaida was originally supposed to be a Bernese Noble, and would have been revealed as Heath's sister.
*** Raven originally had grey hair, and Heath had red hair.
*** The Dancer and Bard rings originally had ribbon icons and could be used as a menu item.
*** The still images were in full colour and did not have a sepia hue over them.
