Trivia / Etrian Odyssey

• Cut Song: "The Battlefield That Never Sleeps" was a track composed for the original game, but ultimately didn't make it into it. However, years later, the Untold remake incorporated it as the theme of the True Final Boss, and this would later be backported to the original via the Origins Collection remaster.
• Uncredited Role: The original party members that speak to the Highlander in the opening cutscene don't have their voice actors listed in the staff roll. Neither in the Japanese or English versions.
• What Could Have Been: Looking into the data of The Millenium Girl reveals plenty of scrapped pieces of script representing content that didn't make it into the final game.
  • Story Mode was apparently a fairly late addition, and the game was supposed to only feature Classic Mode (contrary to the perception of Story Mode taking away content from Classic Mode in the final game).
  • Ren and Tlachtga's third and fourth stratum conversations are not only present in the code, but have Story Mode rewrites as well. These weren't included in the final game due to it making the unlockable classes (which these conversations unlocked) available from the start.
  • The Mauler Mole, a Gladsheim enemy (formerly the Maul enemy from the fifth stratum in the original game), was planned to be an FOE, and has the appropriate animations Dummied Out. Some oddities of this are visible in the final game, as Mauler Moles have a different low-health animation from other moles and cannot flee if they're encountered as a rare breed.
  • There were supposed to be more Guildkeepers; there are only three (one exclusive to Story Mode) in the final game, but the selection menu shows five slots. While one of these Guildkeepers is unaccounted for, the other was supposed to be a duo of eccentric adventurers named Charles and Gaspard who were encountered throughout the Emerald Grove, with the latter temporarily joining the party as a Survivalist.
  • The infamous arc where the party discovers and genocides the Forest Folk was intended to be substantially altered. First, there were new encounters with members of the Forest Folk added in the third stratum to establish them earlier, but the events ended up unimplemented. Second, there would have been some means to take an alternate path through the "Annihilate the Forest Folk" quest, where the party works with Quinn to deliver a letter of peace to Kupala after he discovers that Visil was trying to obfuscate the documents tied to Etria's treaty with the Forest Folk. What's present in the text suggests that not much would change gameplay-wise (the party still has to fight through the Forest Folk to reach Kupala, so she refuses the letter and summons Iwaoropenelep anyway), but it would have allowed a Classic Mode party to spare Kupala and have her as a Guildkeeper (which only happens in Story Mode in the final game). This was also intended to be the same in Story Mode before it received a different justification for the events of the arc.
  • Story Mode was originally going to end with a proper journey through the sixth stratum. To compensate for how high its difficulty is compared to the main game, there would be an option to request help from Frederica, which would highlight the correct path through teleporter mazes and open up shortcuts from the front side. The final game just skips to the 30th floor and the Post-Final Boss for the last leg of the story, with the implication that the party went through the rest offscreen, and the proper runthrough remains in postgame just like the rest of the series. One remnant of this is the presence of many Story Mode events in the sixth stratum; Story Mode in the next game, The Fafnir Knight, doesn't feature any exclusive sixth stratum events since its plot wraps up in the fifth stratum.
