Brutalist city builder BRUT reportedly made with Fable 5.1 in one shot

A user says Fable 5.1 produced BRUT, a brutalist city builder, from a single prompt and calls the result “quite good.” The prompt asks for controls that suit people who just want to play while offering depth for those familiar with architecture. BRUT’s site describes casting concrete structures and studying them under sun, wind, rain and time.
