Yuji Horii, the visionary behind the legendary Dragon Quest franchise, has revealed that he created a new game in just about half an hour using artificial intelligence.
He unveiled this innovative project, a text-based game centered on police interrogations, in a post made on X (formerly known as Twitter). In his announcement, he humorously advised players, “don’t press the boost button.”
Horii emphasized the potential of AI technology, suggesting that even those without artistic or programming skills can develop a solid game by simply providing instructions. He reminisced about his experience with The Portopia Serial Murder Case, a game he developed in 1983 when he handled every aspect of the project himself—from crafting the narrative to programming and artwork.
In the new game, players take on the role of interrogators questioning a 72-year-old suspect named Komiya, a former locksmith, regarding a pawnshop safe burglary. Players must extract statements before a lawyer arrives at 11 PM. The goal is to confront the suspect with evidence, increasing his agitation to make him more likely to confess. However, if he reaches full resistance, he will choose to remain silent.
Horii has explored the integration of AI in gaming previously. Earlier this year, Square Enix collaborated with Google to introduce a Gemini-powered chatbot named Chatty Slimey for Dragon Quest X, which Horii defended in a Famitsu interview, noting it helps gamers engage more readily with AI.
Additionally, Horii is currently involved in developing Dragon Quest 12 and has announced plans for Next: The Portopia Serial Murder Case, which is set to launch in 2027.
In line with these advancements, Unity recently announced Unity Spark, an innovative browser-based solution for creating 3D games using text prompts. This tool is expected to enter beta testing later this year on Google's Playground.
