- Acclaimed Flop: The game did fairly well in the review circuit, but it's one of the lowest-selling Fire Emblem titles ever, even setting aside the small print run. This is the game that first put Fire Emblem on the cancellation brink that Awakening would reverse five years later.
- Cut Song: This game has many songs in its disc that went unused and likely replaced by other songs. Some songs that are remixes of songs from Fire Emblem: Path of Radiance like "On Black Wings" (Naesala's theme), Memory of Mom (Mist's theme), and Victory is Near, were also never used in the game. See the soundtrack page in Serenesforest.net to listen to them. Interestingly, one of the songs (Victory Theme 01) is used in the English version of the game where Micaiah destroys the Blood Pact as it was a scene that only appeared in the localization and not the original.
- I Knew It!: The Black Knight's true identity as Zelgius, as well as Bertram being a Brainwashed and Crazy Renning. Thanks to the magic of hacking Path of Radiance and examining unused files and dummy data, many saw these coming a mile away, although Ranulf spoils the former in Radiant Dawn for those who didn't.
- Keep Circulating the Tapes:
- This game has the second-smallest print run, total, of any Fire Emblem in history, with only Thracia 776 having a smaller original run (and no English-language run), and BS Archanea not really tallying. After Super Smash Bros. and Fire Emblem Awakening made Fire Emblem more popular, and after Fire Emblem Heroes gave the Tellius crew a much greater amount of exposure, interest in the game increased to such a degree that even authentic good-condition discs by themselves can creep up toward $100USD.
- Compounding this is that the game has, to date, not been re-issued in any format; while Wiis are hardly uncommon, you still need appropriate hardware if you want to play the game. And if you want to play Path of Radiance and Radiant Dawn on the same system, using the Wii U's backward compatibility is out of the question due to it being unable to play GameCube games.
- Screwed by the Network: Nintendo wasn't very confident in the Fire Emblem franchise at the time, so they decided to short print Radiant Dawn and release it on the same day as Super Mario Galaxy (one of the Wii's Killer Apps).
- Urban Legend of Zelda: Rumors of additional support paired endings in Radiant Dawn such as Stefan/Soren, Meg/Zihark, and Micaiah/Pelleas abound. Serenes Forest has confirmed they never existed.
- What Could Have Been:
- Radiant Dawn contains data for specific support pairs, but not actual conversations. It's speculated that they were still going to go with the "everyone supports" system but give certain pairs unique conversations for the A rank. Sadly this ended up being dropped.
- Though not confirmed, it is widely speculated that Fiona was supposed to join earlier in the game then she did. This is because her stats when recruited are unusually low for someone nearly level ten, and she joins very late in the first chapter, with the next few levels making her unusable because of terrain. Combined with her level being a bit awkward in terms of where it relates to the others who join around the same time, it appears she was supposed to join at a lower level.
- Some leftover bits of data in Radiant Dawn, plus the fact that male Swordmasters are the only second tier class capable of reaching the SS rank in their primary weapon skill, indicates that Stefan was at some point meant to join the Dawn Brigade in the first act.
- Unused dialogue for Part IV Endgame of Radiant Dawn indicates it was at some point possible to spare the life of Hetzel. His fate wouldn't have been much more pleasant, though, as Sanaki would immediately order him arrested and charged with high treason after the battle.
- Unseen data shows that Levail has his own growth rates rather than using the defaults for his class. Add that to his Resolve skill and general Nice Guy status, and you'll start thinking that he may have been recruitable at one point in time.
- This game has many unused music, one of the most infamous is a remix of Alm's Map Theme #2 from Fire Emblem Gaiden, which implies that this game was originally going to have trial maps like Path of Radiance. One of the original victory themes, however, was re-purposed in the English version of the game as it is used in a cutscene where Micaiah tears the Blood Pact.
