How the AI-Driven Game Controversy Exploded

The fiasco began when Saber Interactive released the announcement trailer for Rideshare Stimulator. Lead writer Stella Sacco, who worked at the studio from July 2023 to July 2024, publicly claimed she was fired and her workload taken over by an LLM without disclosure on the Steam page

2

. He added that he "would frankly in retrospect have been happy to replace her with AI"

Steam Page Updated with Detailed AI Disclaimer

Saber Interactive updated the Steam page for Rideshare Stimulator with comprehensive AI disclosure following the controversy

3

. The AI disclaimer reveals that while the main campaign story, characters, and dialogue are written entirely by human writers, AI-generated content appears elsewhere in the game

3

. AI voice generation powers some character voices, select localization work uses AI tools, and the optional "Free Ride" mode features AI-generated passenger missions and dialogue separate from the core campaign

3

. Additionally, certain in-game radio stations feature AI-generated music, clearly labeled as such

3

. Karch defended the Free Ride mode specifically, noting it required adding two writers and multiple coders to work with AI tools, arguing the net cost ended up higher than simply leaving it out

Portal Writer Chet Faliszek Becomes New Target

Just as the situation appeared to resolve, Karch reignited the controversy by attacking Chet Faliszek, a veteran writer whose credits include Portal, Left 4 Dead, and the Half-Life Episodes

1

. In a LinkedIn post, Karch called Faliszek an "unsuccessful writer" and criticized his 26-minute video titled "Who is the CEO of Saber Interactive?"

1

. Karch wrote that the video "somehow concluded with personal remarks about my physical anatomy and encouragement to accost me," characterizing it as crossing a line from industry analysis into personal insults

1

. Karch later claimed he received death threats as a result of Faliszek's video and accompanying commentary

Ethical Implications of AI Surface in Gaming Industry

The writer replaced by AI controversy highlights growing tensions around AI-generated content in creative industries. Faliszek's primary argument was that Karch's statement to the press was a completely avoidable PR disaster that worsened the controversy

1

. Ironically, Karch's own conclusion in his LinkedIn post was that he should have said nothing and left it to the communication team

1

. Yet he escalated again by providing identifying information about Faliszek's video, effectively expanding the story to "Saber CEO vs. Portal writer"

1

. The ethical implications of AI in creative work remain unresolved, particularly around disclosure requirements and the treatment of human workers. Watch how other game studios respond to pressure for AI transparency on their Steam pages. The Rideshare Stimulator case may set precedents for how companies communicate AI use and handle public criticism when writers are replaced or supplemented by AI tools.
