Square Enix Releases New Version of The Portopia Serial Murder Case With AI-Powered Dialogue
Square Enix, a major video game developer, has announced the release of a new, free version of The Portopia Serial Murder Case, a point-and-click adventure game that was originally released for Japanese PCs in 1983. This new version will feature dialogue powered by AI-driven Natural Language Processing (NLP), which allows players to type or say whatever they want to non-playing characters (NPCs).
The game follows an unnamed detective and their partner as they investigate the death of a successful banking executive. The original game relied on a basic text parser, which allowed players to input commands for their character’s partner to execute upon. However, some players found it frustrating to correctly phrase a command with the text parser, which led to the game’s Famicom release eliminating the text parser in exchange for a more traditional menu system.
The new version of the game uses NLP to determine player intent from significantly more complex sentences, replacing the object-verb system of the original game. This use of NLP in text parsing adventure games is a compelling and relatively uncontroversial application of the technology in video games.
Square Enix refers to the game as an “educational demonstration,” showcasing the broader utility of Natural Language Processing in games. However, the game does not use generative AI for NPC responses, with prewritten dialogue instead.
The game’s Steam page details the technologies used in the game, with the exception of Natural Language Generation, which the company claims to have implemented in a previous version of the game, but not in the current release due to concerns of generating “unethical replies.”
“Unethical replies” likely refers to responses that would break the game, contain discriminatory content, or use specific prompts to get an NPC to reveal the killer. Square Enix states that it will consider reintroducing Natural Language Generation to the game once it can filter out unethical replies.
The choice of The Portopia Serial Murder Case for this experiment is interesting, as the game never received an English official release, making this demo most people’s first exposure to it. Square Enix may be trying to implicitly link the influence of the game that birthed the visual novel to the potential influence of NLPs on the future of game development.
Overall, this new version of The Portopia Serial Murder Case with AI-powered dialogue showcases the potential of NLP in video games, paving the way for more sophisticated and immersive dialogue systems in the future.
