Il creatore di Dragon Quest realizza un gioco con l'IA in 30 minuti
Yuji Horii afferma che l'IA generativa permette anche ai non programmatori di creare da soli un gioco giocabile.

A 30-minute game
Yuji Horii, il creatore di 72 anni della serie Dragon Quest, ha pubblicato un nuovo gioco per browser il 11 ottobre 2026, affermando che gli ci sono voluti solo 30 minuti per realizzarlo 1. Il titolo, "Interrogation Room Komiya," è un giallo poliziesco basato sul testo in cui i giocatori interrogano un sospetto di nome Komiya, un ex fabbro 2.
In un post su X, Horii ha scritto che non ha disegnato le immagini né scritto alcun codice da sé 3. Invece, ha dato istruzioni a un sistema di IA e gli ha lasciato costruire il gioco dai suoi prompt 4. Ha avvisato i lettori di non premere il pulsante di potenziamento all'interno del gioco 1.
From solo coder to AI director
Horii ha raggiunto la fama per la prima volta nel 1983 quando ha creato da solo The Portopia Serial Murder Case su un computer personale 3. Ha scritto la storia, disegnato le illustrazioni e programmato il gioco tutto da sé 2. Ora afferma che è possibile l'approccio opposto: anche qualcuno che non sa disegnare o programmare può creare un buon gioco semplicemente dicendo a un'IA cosa fare .
"It's truly astonishing," Horii wrote in Japanese, translating to: back then I did everything alone, but now with AI even I can make a decent game just by giving instructions 2. He called the shift in game-making genuinely surprising 1.
The game itself
In Interrogation Room Komiya, players take the role of an interrogator facing an elderly suspect 2. The screen shows a recording interface with a clock reading 21:00 and two gauges tracking the suspect's agitation level and resistance . Players have 20 moves to extract the truth before a lawyer arrives at 11 pm 3.
Six questions are available, covering topics like Komiya's whereabouts after midnight, his relationship with a local shop owner, his past as a locksmith, and whether he will discuss his late wife 2. One of those topics, the question about his wife, was marked "no lead" when reporters tried it . A decisive move option unlocks after the player exposes four lies .
A long history with AI
Horii is not new to experimenting with artificial intelligence in games. Earlier this year, Dragon Quest X partnered with Google's Gemini to create a chatbot named Chatty Slimey, an in-game character that talks to players 1. In a Famitsu interview, Horii defended the project by saying modern AI is smart, rarely makes things up, and lowers the barrier for people who want to try chatting with an AI character .
He is also working on Dragon Quest 12 and a surprise sequel to The Portopia Serial Murder Case set to release in 2027 1. The broader game industry has been divided over AI tools, with some developers and actors worried about jobs . This week, Unity revealed a text-prompt 3D game builder called Unity Spark that will enter beta later this year 3.
Horii's 30-minute game post quickly gained traction, reaching 1.9 million views and 16,000 likes on X by the next day 2.
