Dragon Quest's Yuji Horii made a whole game with AI in 30 minutes

Dragon Quest's Yuji Horii made a whole game with AI in 30 minutes. He posted it on 11 October: a mystery game called Interrogation Room Komiya, built by prompting an AI. His 1983 Portopia he wrote, programmed and drew himself. Now he says he can make a decent game alone. He calls the tech astonishing. GamesRadar calls it slop. Dragon Quest 12 has been restarted once already
