- Colbert Bump: The Switch version of the game saw a noticeable boost in interest among western gamers on sale sites such as Amazon after the Hero was introduced as a DLC fighter for Super Smash Bros. Ultimate.
- Fan Nickname:
- Eleven for our hero, since this is the 11th main series Dragon Quest game.
- Eight is used as a codename for Hendrik in order to not spoil his inclusion to the party.
- Meme Acknowledgement: Not in the usual in-joke sense of "meme", but still something that caught on and spread throughout the fandom: In the Switch version's Tickington quests,note the Dragon Quest IX quests involve a dungeon called the "Ruby Path of Doom". Far from just one of IX's randomized grottoes, this is specifically the name of the infamous "Masayuki's Map" that spread through the playerbase because its 15th floor held nothing but Metal King Slimes.
- Milestone Celebration: While not quite released for Dragon Quest's 30th anniversary, the amount of callbacks to the franchise as a whole, and its western release (especially for the Switch version) being 30 years after the original game, help cement it as this for the Dragon Quest franchise.
- Newbie Boom: XI is easily the most successful DQ title internationally since the original trilogy, and has brought in a large number of new players and newfound fans. This helped propel the game into being one of the most successful titles in franchise history.
- No Dub for You: Inverted with the game's initial release in Japan, which had no voice acting at all, while the western release a year later would include English voice acting. It would not be until the Nintendo Switch port in 2019 that the game would finally receive a Japanese voice track as well.
- No Export for You: There are no plans to release the Nintendo 3DS version outside of Japan.
- Troubled Production: Not the game as a whole, but the Switch port specifically. Square Enix claimed the reason that the port took so long is that the original game was built on an older version of Unreal Engine 4 that didn't support the Switch, and that they needed to update the game to a newer version of the engine, which was a significant undertaking. As a result of the Switch version coming out later, the developers chose to incorporate additional content to make up for the delay.
- What Could Have Been: Dragon Quest XI was being considered as an open world title like Breath of the Wild. If one squints a bit, there are definite remnants of this idea in the final game.
