Square Enix tested natural language processing technology in a publicly released tech demo called 'Square Enix AI Tech Preview: The Portopia Serial Murder Case,' launched free on Steam in April 2023. The demo allowed players to type free-form text commands to an NPC partner, with AI interpreting the player's intent rather than requiring exact keyword input.
Details
The Portopia tech preview applied Natural Language Understanding (NLU) to a re-release of the classic 1983 adventure game, enabling the game to understand varied player phrasing rather than requiring precise command inputs. Square Enix described it as an educational demonstration of NLP technology and its potential application to adventure games. A Natural Language Generation (NLG) function was omitted from the release due to risk of the AI generating harmful content; Square Enix stated it would consider reintroducing NLG when safer conditions could be assured. The demo was released free to play on PC via Steam.
