* CreatorBreakdown: The author has admitted that he was suffering from mild depression while writing [[WhamEpisode chapter 15 of ''The Equestrian War'']]. It would certainly explain quite a bit.
* NamesTheSame: [[Franchise/MyLittlePony Firefly and Medley]]. The sequel gives us [[VideoGame/WorldOfWarcraft Deathwing]] and [[WesternAnimation/TransformersPrime Shockwave]].
* WhatCouldHaveBeen: Originally, the author planned to end the first story on the 20th chapter, with [[ResetButton all victims of the war returned back to life]] and, in the case of griffins, reformed for better, due to the influence from Elements of Harmony. Ultimately, he rejected this concept, thinking it would render the entire plot meaningless up to this point.
** One of story concepts was to make the Mane 6 as the main characters of the story and make all of them fly planes, as in actual Ace Combat games. However, the author decided to give the main roles to Rainbow Dash, Fluttershy and some background pegasi, feeling the background characters from the show were "underappreciated" and he hoped to make the story a bit more original when compared to other Ace Combat crossovers, such as ''"Ace Combat: Shattered Rainbows"'' or ''"Ace Combat: Battle for Equestria"''.
* WordOfGod: According to the author, ''The Equestrian War'' is the first story of "Ace Combat: Equestria Chronicles" mini-series, which will contain two stories or a trilogy, provided the second story will be somewhat popular.
** Recently, he confirmed that the plot of ''Ace Combat: Wings of Unity'' will partially revolve around The Crystal Empire, but the Changelings will not appear.
** The griffin soldiers are [[KnownOnlyByTheirNickname known only by their codenames]] and most of them have real life names. The author plans to reveal them in the sequel.
