A dispute has emerged between Epic Games and Valve regarding industry standards and market dominance. Epic Games CEO Tim Sweeney has intensified his criticism of Valve’s mandatory generative AI disclosure policy on Steam, labeling the requirement an “abhorrent” political act and a “witch hunt.” Sweeney argues that forcing developers to disclose AI-assisted assets, such as artwork or narrative, compels studios to make political statements that could be weaponized by “hate mobs” to trigger boycotts. He maintains that AI is a fundamental productivity tool, comparable to compilers or drawing tablets.

In response, industry figures like David Goldfarb, founder of The Outsiders, have defended the policy as a matter of consumer transparency, asserting that “customers have a right to know what they’re buying.” While Valve allows the use of legal generative tools, it requires a dedicated section on store pages to identify AI-assisted content.

This tension unfolds as Epic Games undergoes a strategic pivot toward “full AI acceleration,” integrating generative AI into Unreal Engine, Fortnite, and the Epic Games Launcher to combat rising development costs. 

Separately, former Epic Games engineer Kiaran Ritchie has expressed skepticism regarding the ability of competitors to challenge Steam’s market position. Ritchie argued that user loyalty to established digital libraries and ecosystem features makes it difficult for alternative platforms to gain traction, despite technical improvements or criticisms of Valve’s 30 percent revenue cut.
