An enhanced version, Dragon Quest XI S: Echoes of an Elusive Age – Definitive Edition,[d] was released for the Nintendo Switch in September 2019; for PlayStation 4, Windows, and Xbox One in December 2020; and for Stadia in March 2021.

To increase the awareness of the Dragon Quest franchise in the West, support for Windows and features such as voiced English dialogue and 4K resolution were included.

[2][3] Like with Dragon Quest IX, on land, the game's battle system features no random encounters and shows all enemies on the overworld.

The battle system also adds a free-form camera option inspired by the MMORPG Dragon Quest X that allows the player to move around the enclosed battlefield, although it is purely visual and provides no other benefits to gameplay.

After the protagonist's coming-of-age ceremony, Amber reveals the truth to him about his birth and adoption and sends him to meet King Carnelian of Heliodor.

The pair escape and evade capture, later joined by two mages: Veronica, who is trapped in a child's body due to a curse, and her twin sister, Serena.

The party learns that a prior Luminary named Erdwin was betrayed and killed by his mage companion Morcant, who absorbed Calasmos' powers and transformed into Mordegon.

The party then confronts and destroys Calasmos, before the Luminary entrusts his mark to Serenica, who reverts to her original form and uses it to return to the past and reunite with Erdwin.

[9][10] Initially, the team considered making the game fully open world, but decided against it as it would have led to issues telling its story.

It includes voiced English dialogue, a first-person camera option, support for 4K resolution, and an additional "Draconian Quest" hard mode difficulty feature, among other minor changes.

[19][20][21] Square Enix stated they wanted to expand the Dragon Quest brand outside of Japan, which they believed that these features, in addition to having a Windows version, would assist it.

[10] Known as Dragon Quest XI S: Echoes of an Elusive Age - Definitive Edition, it was released worldwide on September 27, 2019, and features English and Japanese voice acting, with the English voice acting being available as an add-on in the Japanese Switch version, a 16-bit graphical mode adapted from the 3DS version, an option for orchestral music (with "Overture XI", a version of the series' main theme, from the game's opening movie, being re-orchestrated, which was taken from the orchestrated soundtrack, as with the other tracks in the game), and expanded plot elements.

Polygon stated that the upgraded visuals and presentation were "grafted onto a frail and aging skeleton" and that it was unlikely to bring in any new fans to the series due to its non-evolving nature.

[50] PC Gamer agreed, noting that while the Windows port ran without issue and "looked great," they believed the game itself was "disappointingly safe.

[53] In North America, the game had the best launch month in series history, doubling the dollar sales of the previous best, Dragon Quest IX.

[58] The Luminary appeared as a playable character via downloadable content in the 2018 crossover fighting game Super Smash Bros.
