- Broken Base: Many fans did not react well upon finding out that the iOS and Android versions of the game left out the popular Pachisi / Treasures n' Trapdoors and Monster Medals sidequests and decided to pass on them.
- Demonic Spiders: The chest monsters. Man-eating chests can kill your party in one or two attacks when you first meet them, while Mimics have a One-Hit Kill spell that will try to kill your party members.
- Ensemble Dark Horse: The warriors in general, though the female warrior most distinctly. She appears as various NPC's in future installments of the series. The male martial artist has likewise gone on to appear in future games, as well.
- Fan-Preferred Couple:
- In Japan, it is all but a sniff from universally accepted fanon that the Male Hero and the Female Sage are an item and are the couple who start the trilogy's legendary family line. The only quibble in this is what Sage starts off as — there's far less agreement over whether she begins as a Jester, Cleric, or Mage.
- Dragon Quest XI brings this to a kind of level of Ascended Fanon, since the heroes who reference the DQ3 cast are formed around a male hero and female sage who start the legendary line of that game... and the bonus ending shows that Erdrick is descended from those heroes, meaning that a male Erdrick falling for a female Sage would be a case of History Repeats, which the wider cycle has as a bit of a theme.
- "Funny Aneurysm" Moment: One of the towns in this game is called Isis. While it's almost certainly named after the Egyptian goddess, who's a decidedly-benevolent figure, a lot of people are likely to have different associations with that name, as of this writing.
- Depending on when your Mage or Sage gets it, the Transform spell can qualify as one. Having two or more of your best ally? Yes, please! Not much gear though, until the remakes threw in quite a handful. (The best is the Rubiss Sword, which has a colossal + 160 attack bonus, casts Thordain for free when used as an item, and everyone can use and equip it with no penalties.)
- Somewhat oddly, the Golden Claw of all things, especially in the remakes. By itself it's powerful but not super game-breaking; in the original release, it can't even really be used as a weapon, practically. However, getting out of the pyramid with it puts you in a ton of fights... Which is the point, right? Except it puts you in a ton of fights, which means if you pull it off, you just came out of a hypercharged grind session and are swimming in money and experience even without selling the damn things. It's far worse in all remakes, where you have the "bag" and can bring dozens of cheap healing herbs along, and conceivably get the claws out very soon after reaching the Pyramid initially. Pull that off, and not only does your Fighter have a weapon better than anything store-buyable but you've just pulled off a speed-grinding session that gives you all the money you'll need for a large chunk of the game and probably gave your entire team several levels in the space of two dungeon floors.
- If you have the first three characters select "Parry" and then cancel all the way to the first when it is time to select the fourth character's command. This will allow you to attack normally, but your characters will take damage as if they had parried.
- Good Bad Bugs: The Item glitch. The glitch works like this- form a party. Allow one member to die and then go to Luisa's and remove the dead character. Get a new character and then allow 3 party members to die. Normally in game play, if you have three dead party members the game will not allow you to switch out the living party member for a dead one at Luisa's. However, if the living party member has the Numb status, then the game will let you exchange the character for a dead one. You will now have a party of all dead characters. Go to the overworld and just take a few steps and watch your inventory go nuts.
- Growing the Beard: The first two games certainly weren't unpopular, but it was DQIII which set the franchise's place in history and the collective consciousness of Japan in marble. It was a lot more polished than the first two, far broader in scope, and however many arguments might be made for exactly how much influence the game had on JRPG's as a whole, the game's influence on its successors is absolutely humongous, as each one more or less tries to live up to the standard it set and mix up the formula it established, for good or ill.
- Heartwarming Moments: In The Remake you can wish Ortega back to life. Doing so allows the hero to see their parents' touching reunion. It also means even if the hero is trapped in Alefgard after defeating Zoma, at least their mother will not be alone, and the heroic bloodline can continue in both worlds.
- Hilarious in Hindsight: The game's almighty influence on JRPGs also tended to affect the Light Novel and Web Novel scene of the New Tens, especially the Trapped in Another World/Reincarnate In Another World subgenre of stories that were popular then. That tidbit is very funny in hindsight, given that ultimately, Erdrick himself is also a hero from another world who saves the realm.
- It Was His Sled: While frequently referred to as part of the Erdrick trilogy nowadays, three quarters of the game's length try to present it as independent of the first two titles.
- Baramos is a Disc-One Final Boss.
- Memetic Molester: The male Jester among the Japanese fandom.
- "Seinfeld" Is Unfunny: While the game has aged very well, especially with the remakes, many modern gamers miss just how groundbreaking this game really was at the time. It is the Ur-Example, Trope Makers, and Trope Codifier of many, many JRPG tropes. To truly cement this in one's mind, consider the following — Dragon Quest III came out a scant 2 months after Final Fantasy I.
- Tear Jerker: After following Ortega's footsteps throughout the entire game, you encounter him in the final castle... Right before The Dragon kills him in front of you.
- The Hero's poor mother. Her husband Ortega is presumed dead and she sends her only child to fight evil. The child vanishes just like her husband and then the child is sealed away in Alefgard. Now the mother has lost her husband and will never see her only child again.
- Try talking to the Hero's Mother while the Hero is dead in your party. The poor woman nearly breaks down completely.
- That One Boss: Kandar is possibly the first difficult fight in the game. Until you find out he has a crippling weakness to the Sleep spell.
- That One Level: The cave to the Necrogond. Not nearly as frustrating as the Road to Rhone in the previous game, but tough nonetheless.
- Values Resonance: The fact that you can have any playable character be any gender in any role. Want a full team where everyone is an Action Girl, including the main character? You can do that. This was certainly a very forward thinking feature, especially considering this is from an NES game released in The '80s, where most girl characters in games were relegated to the Damsel in Distress role (though even then there were exceptions).
- Visual Effects of Awesome: The Game Boy Color re-release of the game faithfully recreates many of the visual effects of the SNES release, including a complete remake of the opening sequence, the battle over the volcano included.
- Woolseyism: The English name Xenlon goes quite well with the character, as she's basically a Lawyer-Friendly Cameo of Shenron of Dragon Ball Z. They even look similar!
