Square Enix brought back the Yuji Horii PC-6001, MSX, and Famicom game The Portopia Serial Murder Case as an NLP AI tech preview. It is available on Steam in both English and Japanese on April 24, 2023. It will be a free-to-play example of AI with natural language processing, natural language understanding, and speech to text. However, the official site noted that there is no natural language generation for game characters’ responses due to “a risk of the AI generating unethical replies.” However, that could eventually appear.

In The Portopia Serial Murder Case, players are a detective who works alongside their partner Yasu to investigate the death of a Mr. Yamakawa. Players input actual text to direct Yasu to act or investigate and solve the crime.

Here are some of the initial screenshots.

The original Yuji Horii adventure game first never appeared outside Japan, though it did appear on multiple platforms. It debuted on the PC-6001, then eventually came to the MSX and Famicom before heading to mobile devices.
