Saber and a former lead writer are publicly disputing how artificial intelligence was used in Rideshare Stimulator, a game announced last month and developed by Unigine. Stella Sacco, who says she was the project’s lead writer, wrote on Bluesky that Saber replaced her with ChatGPT midway through development. She also alleged that all passenger voices were generated by AI, adding that the companies either later changed direction or had not disclosed the technology’s use on Steam. Saber CEO Matthew Karch denied that Saber or Unigine had replaced any writers with AI. In a statement to The Verge, he said the game’s story was written entirely by people apart from one experimental mode. Karch acknowledged that the experimental “free-ride mode” uses AI because the number of passengers is infinite. He said Saber has used AI tools to enhance gameplay and non-player character behavior since the company was founded in 2001. He also said Saber continues to hire and that none of its more than 3,000 employees should worry about being replaced by AI. Sacco told The Verge that she was indignant at what she viewed as being called a liar. She argued that the company could not meaningfully claim writers produced the story while also acknowledging that computers generate text. She maintained that if the game includes rides she wrote alongside rides written, or yet to be written, by AI, then AI was still used and she was still replaced. Sacco said Saber had told her that this was happening in December 2023 and accused the company of trying to have the issue both ways. The dispute gives Somali players a concrete reason to examine where human-written material ends and AI-generated dialogue begins when the game becomes available.
