Saber Interactive CEO Apologizes to Former Lead Writer Following AI Replacement Dispute
Saber Interactive CEO Matt Karch issued a private apology to former lead writer Stella Sacco after a public dispute over the use of generative AI in the upcoming game Rideshare Stimulator.

What everyone gets wrong about the integration of generative AI in video games is the assumption that it will be a seamless, invisible backend upgrade. The evidence points to the exact opposite: the transition is arriving through messy, highly public labor disputes and reputational crises. The industry's latest flashpoint is a prime example, centering on a week-long public meltdown by the CEO of Saber Interactive over the upcoming simulation game Rideshare Stimulator.[1][2]
At the heart of the controversy is a fundamental clash over creative ownership, labor replacement, and consumer transparency. The dispute erupted when Stella Sacco, a veteran narrative designer and former lead writer on Rideshare Stimulator, publicly alleged that she was removed from the project midway through development and replaced by ChatGPT.[1][2][4]
Sacco's claim struck a nerve in an industry already on edge about generative text and voice tools. She stated that the decision to pivot to AI came from Saber's executive level, warning them at the time that players would reject the technology. Furthermore, she highlighted a critical compliance issue: the game's Steam store page contained no disclosure regarding its use of generative AI.[2][5]
Saber Interactive initially issued a boilerplate denial, stating that no writers had been replaced by AI for Rideshare Stimulator or any other title. The publisher insisted that the game's core story was written entirely by human developers, attempting to quell the growing backlash from players and industry peers.[2][5]
The situation rapidly deteriorated when Saber CEO Matt Karch issued a combative and highly personal statement to the press. Rather than de-escalating, Karch claimed Sacco had violated a confidentiality agreement and mocked her professional standing. "Stella who? I had to ask Claude because I have never spoken to her or seen her," Karch wrote, referencing Anthropic's AI chatbot.[2][5]
Karch's statement went further, asserting that Sacco was replaced by "someone more talented" and adding a provocative defense of algorithmic generation. "I would frankly in retrospect have been happy to replace her with AI," Karch stated. "At least we would be dealing with someone programmed to be honest."[2][5][6]
The CEO's outburst triggered immediate and widespread condemnation across the gaming industry. Veteran developers, including former Valve narrative lead Chet Faliszek—known for his work on Portal and Left 4 Dead—publicly criticized Karch's handling of the situation. Karch subsequently took a jab at Faliszek on LinkedIn, further fueling the PR disaster.[3]
After days of intense online scrutiny and reputational damage, the standoff culminated in a sudden reversal. Sacco took to the social media platform Bluesky to confirm that Karch had sent her a lengthy, private email apologizing "unreservedly for the awful way he spoke about me in the press."[1][4][6]
Sacco accepted the apology, noting that while she and Karch still fundamentally disagree on the ethics of AI in game development, she wanted to put an end to the public harassment. "Apologies are simply in too short a supply these days to spurn one when it's offered," Sacco wrote, emphasizing that the consequences of AI adoption ultimately fall on executives and their employees.[4][6]
Beyond the interpersonal drama, the dispute forced a reckoning with platform regulations. Valve, the company behind the dominant PC storefront Steam, implemented strict new rules regarding generative AI in early 2024. Developers are now required to disclose whether their games use "Pre-Generated" AI content (assets created during development) or "Live-Generated" AI content (created in real-time while the game is running).[2][6]
Under pressure from the public dispute, Saber Interactive finally updated the Rideshare Stimulator Steam page to comply with these transparency mandates. The disclosure revealed the actual mechanism of AI integration within the game, drawing a line between traditional narrative design and algorithmic features.[6]
According to the new store page details, the game's main campaign script remains human-written. However, generative AI tools are actively deployed for voice generation, localization, and a specific "Free Ride" mode. In this mode, the AI dynamically generates passenger dialogue to create an "infinite" number of interactions for players driving around the virtual city.[6]
This specific use case—infinite, dynamically generated dialogue—represents the exact frontier where human writers and AI tools are currently clashing. Executives view live-generated text as a cost-effective feature that adds endless replayability to lower-priced titles. Writers view it as a direct threat to narrative quality and a tool used to justify shrinking creative teams.[1][5]
The Saber Interactive dispute serves as a high-stakes precedent for the gaming industry. It demonstrates that the implementation of generative AI cannot be quietly slipped into a game's backend without risking severe pushback from both the developers who build the games and the players who buy them.[2][5]
As more studios experiment with large language models and AI voice generation, the friction between creative labor and algorithmic efficiency will only intensify. The Rideshare Stimulator controversy proves that the battle over AI in gaming won't just be fought in boardrooms and codebases—it will be fought loudly, and publicly, in the open.[1][6]
