What happened
- Rideshare "Stimulator" is an upcoming driving game developed by Unigine and published by Saber, in which players operate a rideshare business transporting passengers with different stories and personalities.
- A dispute between Saber Interactive and a former writer has escalated into a public war of words.
- Former Saber lead writer Stella Sacco wrote: "I didn't even see this had been announced. I was lead writer on this one! And Saber replaced me with ChatGPT midway through development. All the passenger voices were AI too. Either they changed direction at some point, or they're not disclosing it on Steam."
- In a statement to PC Gamer, Saber said: "Neither Saber nor Unigine have replaced any writers with AI for Rideshare or any other game."
- The same Saber statement said: "In fact, Saber's staff of writers has tripled since 2023."

Why it matters
Saber Interactive and a former lead writer are trading public statements over whether generative AI took her job on Rideshare "Stimulator", an unreleased driving game developed by Unigine and published by Saber [1][2]. No outsider can settle who wrote which lines, but the argument has produced one artifact anyone can check: the game's Steam page, which by the CEO's own account does not yet describe the AI features the company says are in the game [8][9].
The sequence, as reported by Dexerto: shortly after the game surfaced online, former Saber lead writer Stella Sacco wrote that Saber "replaced me with ChatGPT midway through development", that "all the passenger voices were AI too", and that either the direction changed "or they're not disclosing it on Steam" [3]. Saber told PC Gamer that "neither Saber nor Unigine have replaced any writers with AI for Rideshare or any other game", that "Saber's staff of writers has tripled since 2023", and that "Rideshare's story was written entirely by real people" [4][5][6]. The same statement confirmed that an experimental free-ride mode will incorporate AI, on the grounds that the number of possible passengers there is infinite [7].
Read closely, the denial and the confirmation are not in conflict, and neither addresses the specific thing Sacco alleged. Saber's denial covers the replacement of writers and the authorship of the story; Sacco's claim was about the passenger voices, which is roughly the territory the free-ride mode occupies [18].
CEO Matthew Karch then went further. "Stella who? I had to ask Claude because I have never spoken to her or seen her," he said in a statement to This Week in Videogames [10]. He added that Saber has "already said we are using AI for certain parts of the game and will update the Steam page once we have finalized the feature set" [8], that a story-script award would go "to someone who can walk up on stage and receive it" [11], and that it was "always our intention to reveal this until Stella violated her confidentiality clause and revealed this before we were ready" [12]. He also said Sacco was replaced by "someone more talented" and terminated for other reasons a few months later [13], and that in hindsight he would have been happy to replace her with AI, since AI is at least "programmed to be honest" [14].
That is the part to isolate. Karch is not denying AI in the product; he is arguing about sequencing, that disclosure was coming and Sacco pre-empted it [8][12][19]. That turns a labour dispute into a disclosure dispute, and the buyer-facing question is only whether the store page describes the product at the point of sale, not whether an internal reveal schedule was disrupted.
The headcount defence does not settle anything either, because "tripled since 2023" is given without a baseline, so it is not checkable from outside [5][20]. Sacco stands by her account and says Karch is "lashing out because he did not want people to know there was AI use in the game" [15]; she also argued the statement would damage Saber's reputation more than hers [16]. The two accounts remain irreconcilable [17].
Watch whether the Rideshare Steam page carries an AI disclosure before or at launch, and whether it is scoped only to the free-ride mode or extends to passenger dialogue [7][8]. Watch, too, the claim that describing your own replacement breaches a confidentiality clause, which is a precedent with reach beyond one driving game [12].
