S&box creator Garry Newman vows to combat AI slop flooding Garry's Mod successor

S&box Launches Amid AI Content Controversy

The Garry's Mod successor s&box released on Steam this week, but its debut has been overshadowed by an unexpected challenge. The game development platform, designed as an open-source toolkit built on a heavily modified Source 2 engine, is grappling with an influx of AI slop that's dominating its main page 1

. At the time of writing, s&box holds mixed Steam reviews, with the vast majority of negative feedback citing low quality AI contributions as the primary concern 2

Steam reviewers have been vocal about their frustration. One reviewer described the platform as "AI-infested," while others noted the prevalence of asset flip games and gambling simulators cluttering the user-created games section 3

. The community's concerns center on whether Facepunch Studios is adequately moderating AI content or inadvertently enabling creators who rely entirely on generative AI rather than genuine human effort.

Garry Newman Addresses the AI Slop Problem

Garry Newman, founder of Facepunch Studios and creator of the original Garry's Mod, responded directly to the criticism in a statement to Rock Paper Shotgun. "Low quality, obvious AI-created slop is going to be a growing problem in every creative outlet," Newman acknowledged. "We don't encourage using AI to be creative. We don't encourage using AI to create games for you" 1

. He committed to pushing AI-generated content off the main page and taking action to promote human creativity across the platform 2

Yet Newman's stance on AI reveals nuance. While emphasizing that Facepunch doesn't AI generate anything for s&box itself, he recognizes AI as a productivity tool that can accelerate development workflows 2

. Speaking at GDC before the launch, Newman explained his philosophy on moderating AI content: "My general thing with moderation is you want something to moderate before you create a system to moderate it" 1

The Challenge of Moderating User-Generated Content

Facepunch Studios faces a significant challenge in balancing openness with quality control on its game development platform. Newman believes that "eventually the slop will just fall to the bottom" as users recognize and avoid obviously AI-generated projects 1

. The studio plans to implement a weekly cadence of updates with close attention to player feedback, though they acknowledge s&box "isn't perfect" at launch 1

.

The moderation dilemma extends beyond simple detection. Facepunch doesn't want to discourage contributions or police the origins of every asset in each submission—a task that would be nearly impossible at scale 2

. The studio has also partnered with Valve to allow creators to publish their s&box creations as standalone games on Steam, raising concerns about whether this could open the floodgates to even more AI-generated games on the platform 3

What This Means for Game Development Platforms

The s&box situation highlights a broader challenge facing user-generated content platforms like Roblox and similar creative outlets in 2026. As generative AI tools become more accessible, distinguishing between human creativity and automated content generation becomes increasingly difficult. Some reviewers have noted that the game has attracted interest from NFTs and crypto communities, potentially complicating Facepunch's moderation efforts further 3

. The studio may need to decide whether alienating certain user segments is acceptable to maintain the creative vision they want to cultivate. For now, removing the spotlight from AI-heavy submissions appears to be the middle ground Facepunch is pursuing, though the long-term effectiveness of this approach remains to be seen.
