Yuji Horii

Yuji Horii released Komiya in the Interrogation Room, a short browser game he says he built in about 30 minutes by directing AI, on October 11, 2026. Earlier in 2026 he advised the Switch board game Karma x Cross, and he marked the Dragon Quest series' 40th anniversary in May.

Synthesized from 4 Yomimono stories · updated 2d ago

Yuji Horii's 2026 activity spans three different kinds of work. In May, the Dragon Quest series turned 40. Horii, credited as the series' creator, posted a congratulation along with former series director Jin Fujisawa, voice actors, and the official Final Fantasy account. The franchise began in 1986 with a command-based RPG that helped popularize the genre in Japan.

In August, Horii was named advisor on Tensei Game Karma x Cross, a download-only Nintendo Switch board game from Any Inc. and ArtePiazza. It is a sugoroku party game about four people who died in accidents competing for limited reincarnation slots, and it released on August 6 at 3,980 yen. The same game carries an original concept by Muneyuki Kaneshiro, character design by Shintaro Majima, game design by Ayaka Sato, and direction by Sachiko Sugimura.

In October, Horii released a game of his own. Komiya in the Interrogation Room is a short browser adventure in which the player interrogates an old man named Komiya about a safe burglary. Horii said production took about 30 minutes and that giving instructions to AI can produce a reasonably good game. The game clears in about 5 to 10 minutes.

Between those, G-Mode announced The Portopia Serial Murder Case Continued: Burial of Oblivion at the September 9, 2026 Nintendo Direct. Horii is not credited in that announcement; the project is G-Mode's, structured like the Hokkaido Serial Murder: Murder on the Okhotsk remake with a full remake of the original plus a new story, and the Okhotsk team is handling it.
