Key information

Yuji Horii, the creator of the Dragon Quest series, recently shared his experience using artificial intelligence to develop a game. He reflected on his past work on the 1983 title The Portopia Serial Murder Case, noting that he previously handled every aspect of development alone, including narrative design, illustration, and programming.

The developer expressed astonishment at how modern generative AI tools allow individuals to create functional games without needing specialized skills in coding or graphic design. By simply providing instructions to an AI, Horii noted that one can produce a decent game in a very short timeframe.

Horii demonstrated this capability by creating a new mystery game using Claude. He revealed that the entire production process for this project took only about 30 minutes to complete, a stark contrast to the manual labor required for his earlier pioneering adventure titles.

The resulting game is currently available for users to play via a link shared by Horii. The Portopia Serial Murder Case remains a significant historical title in the adventure genre, known for its command-based investigation mechanics and its famous plot twist.
