Earlier this morning, Square Enix hosted a Dragon Quest 35th Anniversary stream, which featured some new Dragon Quest games that will be released. Among the reveals was the announcement that Dragon Quest III will be receiving a 2D-3D remake. As the trailer shows the game seems to be following the artstyle as seen in Octopath Traveler. Dragon Quest III HD-2D Remake is set to have a simultaneous worldwide release, however currently no official release date or release platforms have been confirmed at this time.
For those who are not aware, Dragon Quest III was originally released for Famicom and the NES on February 10, 1988. When the game was localized in North America it went under the title, “Dragon Warrior III.” In Japan, an enhanced remake of the game was released for the Super Famicom in 1996 and also the Game Boy Color in 2001. The game also received a port on mobile phones and the Wii in 2009 and 2011, respectively. Another version of the game was released for Android and i0S in 2014 in Japan and later worldwide under the name Dragon Quest III: The Seeds of Salvation in 2014. An updated version of the game was also released for the Nintendo 3DS and Playstation 4 in 2017. This version also was ported to the Nintendo Switch in 2019.
