Valve tightens Steam review rules amid AI project influx

Valve has updated its game review guidelines prior to publication on Steam, extending the expected review time from the usual 3–5 days to up to 12 business days. These changes aim to reduce the massive backlog of submissions and prevent repeated build rejections. The updates come amid a sharp surge in new game releases on the platform.

• Steam review times increased up to 12 business days due to queue backlog.
• Mandatory requirement to run the game via Steam client for at least 5 minutes before submission.
• Pre-check required for DirectX, Visual C++, achievements, and Steam Cloud settings.
• Surge in low-quality AI projects adding significant pressure to the moderation queue.

New pre-testing requirements for developers

Before submitting a build for review, developers must now launch the game directly through the Steam client and ensure it runs properly on the platform for at least 5 minutes. Previously, some creators limited their tests to running the executable file directly, which caused them to miss issues that only emerge during installation and startup through the Steam client.

Additionally, Valve now requires preliminary verification of common component installations, including DirectX and Visual C++, along with checking achievement readiness and proper Steam Cloud save configurations. Screenshots must also be properly categorized into gameplay, menus, concept art, or video trailers. The company expects these extra developer-side checks to reduce the number of rejected builds.

The impact of the artificial intelligence boom

While Valve did not explicitly link the queue delays to AI-generated games, independent developer 2 Left Thumbs suggested that a flood of low-quality projects appearing in September and October contributed to the backlog. According to Reddit data, 49.9% of games released on Steam in October disclosed the use of AI-generated content. Back in June, nearly 20% of demo games participating in Steam Next Fest reported similar usage.

This massive influx of automated or low-effort content has put an immense strain on Valve's review pipeline, necessitating stricter upfront controls and procedural updates. As generative tools become more accessible, platform moderators face unprecedented volumes of incoming submissions that require careful oversight.

Consequences for independent developers

These delays are already impacting independent developers, for whom strict marketing schedules are vital. The creator of Cubic Earth told PC Gamer that their game's trailer surpassed 60,000 views on YouTube, and wishlists exceeded 6,000 additions.

However, due to publication delays, community pages began filling up with player complaints, causing initial launch interest to wane. With review times stretched out, developers must now factor in nearly two weeks of buffer time before planning major promotional pushes.
