Tim Sweeney is at it again. The Epic Games CEO posted on X that "Valve has held gaming back for years by locking developers' PC games into Steamworks' social walled garden," arguing that players on iOS, Android, Xbox, PlayStation, Switch, and other PC stores cannot communicate with Steam players. It is the latest in a long series of very public jabs at Valve and Gabe Newell.
What Sweeney actually said and why it matters now
The timing is hard to ignore. Less than two weeks after Epic relaunched its storefront with what the company described as a "vibe coded" launcher built for speed, Sweeney jumped into a thread started by former Epic Games principal animation programmer Kiaran Ritchie. Ritchie had posted that the industry is "drained by a 30% tax on gross revenue" and suggested someone could "vibe code a Steam alternative in a week" given that "Steam's only remaining value is its network."
Sweeney agreed, then went further. His specific claim is that Steamworks' social layer, the friends lists, matchmaking, and communication tools baked into the platform, creates a barrier between Steam players and players on every other platform. The implication is that this fragmentation benefits Valve by keeping players tied to Steam, at the expense of the broader ecosystem.
Here's the thing: a community note was attached to Sweeney's post almost immediately. The Steamworks documentation publicly shows that developers can use Steam Datagram Relay, Valve's virtual private gaming network, on non-Steam platforms as long as the game ships on Steam. That is not a full rebuttal of the walled garden argument, but it does complicate the picture considerably.
A pattern that goes back further than this week
This is not an isolated comment. Sweeney has supported a $900 million lawsuit against Valve over Steam's revenue cut, called Steam's AI disclosure requirements "really irresponsible," and took shots at Newell after the Steam Deck received a price increase. The through-line in all of it is the 30% revenue share that Steam takes from developers, a figure Epic challenged directly when it launched the Epic Games Store with a 12% cut.
What makes this particular comment land differently is the Steamworks angle. Sweeney is not just complaining about fees this time. He is arguing that Steam's social infrastructure is actively harmful to cross-platform play and developer freedom. That is a more substantive technical claim than "the cut is too high," and it is one that developers actually care about when they are deciding where to launch.
The counter-argument Valve does not need to make
Valve has not responded, and it rarely does. The company's track record speaks in a different direction than Sweeney's framing suggests. Proton, Valve's compatibility layer, has done more to open PC gaming to Linux users than anything Epic has shipped. The Steam Deck normalized handheld PC gaming at scale. Steam's library of over 50,000 games, its refund policy, its Workshop modding tools, and its offline mode are features the Epic Games Store spent years trying to match.
None of that makes the 30% cut defensible on its own merits, and the Steamworks walled garden point is worth debating seriously. But framing Valve as the entity that "held gaming back" while Epic was busy locking games to its own store with timed exclusivity deals is a position that requires some selective memory.
The Epic Games Store has made real progress. Its launcher is faster. Its free game program has been genuinely good for players. For Fortnite players specifically, getting the most out of Epic's platform means knowing the tools available to you, from optimizing your FPS settings to finding the latest Override Lobby Hack codes for Chapter 7 Season 4.
Sweeney's frustration with Valve's dominance is real and, in some respects, legitimate. But the argument that Valve specifically held gaming back sits awkwardly next to the Steam Deck's Linux contributions and Proton's ongoing development. The cross-platform social layer debate is a more interesting conversation than the fee argument, and it deserves a more precise framing than a post on X. Keep an eye on how developers respond to this one, because their perspective on Steamworks integration will carry more weight than either CEO's public positioning.
