Dragon Quest creator makes interrogation game in 30 minutes with AI
Yuji Horii says he built a playable crime interrogation game in about 30 minutes using generative AI.
The creator of Dragon Quest, the long-running role-playing series about heroes, monsters and turn-based battles, showed off the experiment in a post on X. The project is called Interrogation Room Komiya, according to Video Games Chronicle. The post linked to a version fans can try. Followers could click through and start questioning within seconds.
In Interrogation Room Komiya, players work through a police interview. You choose from text prompts on screen. Each choice pushes the suspect closer to a confession — or lets him slip away. There are no long tutorials to learn. Read, choose, watch the reaction.
Horii said the build took about half an hour. That is the claim. He put it down to generative AI, software that can write text, draw images and produce working code from written instructions. Give it a clear brief in plain language and it returns a playable result.
He said he simply gave instructions to the system. No drawing pictures. No writing programming code by hand. The AI handled the production steps from draft to playable file.
That is a sharp change from how he described his early work. Horii said he created the story, pictures and programming himself for The Portopia Serial Murder Case, his detective adventure about tracking a killer. That game required hands-on craft at every stage. This one required prompts. One method took sustained solo labour. The other took a short conversation with a machine.
Horii has been open about his curiosity around AI characters. He has said AI pals are "not just a convenient tool but a friend to each individual player," according to Eurogamer. The comment came in May. It framed AI companions as personal presences rather than helpers in a menu. The new experiment puts that idea into practice on a very small scale.
He also looks outside his own series for inspiration. He has called Final Fantasy X, the 2001 role-playing game from rival maker Square, "ultimate perfection" at release, according to IGN. That history matters here. Horii knows big productions that take years and large teams.
What makes this stand out is the contrast in effort. One short session. One set of instructions. A complete questioning loop. For fans, this means a rare chance to play something tiny and direct from a designer best known for epics that take dozens of hours.
