Horii said AI means people can now make a decent game alone, even if they can't draw or program

Yuji Horii, the creator of Dragon Quest, says he has produced a new game using AI in about 30 minutes.

Horii shared the game, a text-based police interrogation game, in a post on X/Twitter. He said it took about 30 minutes to make, and told players "don't press the boost button."

He said that with AI, people can now make a decent game alone by giving it instructions, even if they can't draw or program. He compared this to making The Portopia Serial Murder Case in 1983: "I came up with the story myself, drew the pictures myself, did the programming myself, and created the game all by myself."

In the game, players question a 72-year-old suspect, a former locksmith named Komiya, over a break-in at a pawnshop's safe. Players have until a lawyer arrives at 11pm to draw out statements, then confront the suspect's lies with evidence. The higher his agitation, the easier he is to crack, but if his resistance reaches 100, he stays silent.

Horii has previously worked with AI in games, and Square Enix partnered with Google earlier this year to add a Gemini-powered chatbot called Chatty Slimey to Dragon Quest X.

In a Famitsu interview, also earlier this year, Horii defended the decision, saying that the chatbot makes it easier for people to start interacting with AI.

He is also involved with Dragon Quest 12 and Next: The Portopia Serial Murder Case, which was announced in September for 2027.

Unity recently unveiled Unity Spark, a browser-based tool for building 3D games with text prompts, which will launch in beta later this year on Google's Playground.
