Saber Interactive has added an AI-use disclosure to Rideshare Stimulator‘s Steam store page after a public dispute with former writer Stella Sacco. The notice was not present when the game’s Steam page went live on July 30, 2026, but it now appears on the listing.
Sacco previously said she was removed from the project in 2023 and replaced “with ChatGPT” in a Bluesky post. Saber CEO Matt Karch rejected the claim that the company replaced her with AI, while acknowledging that generative AI was used for parts of the game. Karch’s earlier response to Sacco’s claim offered the company’s account of her departure.
In comments sent to This Week in Videogames, Karch said Saber had always intended to disclose its AI use after finalizing the feature set. He also accused Sacco of breaking a confidentiality clause by discussing the project before the company was ready to make the information public.
What Saber’s Steam disclosure covers
The notice says the main Campaign story, characters, and dialogue are written by a team of human writers. It also says AI tools are used for voice generation and some localization. The optional Free Ride mode includes AI-generated passenger missions and localized dialogue. Because Free Ride is separate from the main Campaign, players can skip it if they prefer to experience only human-written narrative content. The Rideshare Stimulator Steam page now carries the disclosure.
The notice also refers to AI-generated dialogue and says the game includes a mix of human-made and AI-generated music. Radio stations that contain AI-generated music are identified inside the game, giving players a way to distinguish those stations from the rest of the soundtrack.
In an interview with IGN, Karch said the experimental mode required two writers and several coders to work with AI tools, adding that the total cost of including the features was higher than leaving them out.
Despite that expense, Karch said he was willing to discuss how “AI can and should help shape gamer experiences.” He also described the dispute as a publicity stunt and said Saber’s writing staff had grown since 2023.
Sacco later disputed that framing. In a follow-up Bluesky post, she called the new disclosure worse than what she had originally described. In another statement, she maintained that her earlier claims were true and argued that Karch’s comments, combined with the game’s AI use, would cause more harm to Saber’s reputation.
The new disclosure gives players more information about how Rideshare Stimulator was made, but it does not settle the disagreement over Sacco’s role or the extent of AI’s involvement in development. For now, Saber’s public position is that AI was used for a limited experimental feature rather than as a replacement for the game’s entire writing process.
