Steam Game Reviews Stretch to 12 Business Days as Valve Changes Submission Rules Amid AI-Content Debate

Valve says Steam has received a significant increase in store-page and game-build submissions in recent months, pushing review times from the usual three to five business days to as many as 12 business days. On November 3, the company published an updated release checklist intended to reduce repeat reviews caused by basic functional problems and help developers pass the process on their first submission.

The changes come as the number of games released on Steam and the use of generative AI in game content are both attracting attention. A third-party analysis reported that 49.9% of new Steam games released in October 2026 disclosed some use of AI-generated content. But Valve has not said that AI games caused the review backlog. The company attributed much of the delay to having to review builds again after initial problems, so the industry’s concern about AI-generated low-quality games should not be presented as Valve’s confirmed explanation.

Review times rise from three to five days to as many as 12

In its Steamworks developer announcement, Valve said submissions for store-page and build reviews had increased significantly. The company said it normally aims to test a game build within three to five business days, but is currently taking as long as 12 business days. Valve said much of the delay comes from having to review the same game again after an initial submission fails.

The longer queue has affected independent developers whose release dates are tied to marketing plans, press coverage and promotional events. The Verge reported that some studios had missed planned launch dates while waiting for approval. Valve said the revised checklist is designed to reduce repeat submissions caused by basic functional issues, and that more improvements to the review process are in development.

Developers must launch their games through Steam before review

The new checklist asks developers to run their game through Steam’s Play button for at least five minutes before submitting a build. Valve said some games had been submitted for review without ever being launched through Steam. A game might appear to work when a developer starts its executable directly, but still have problems with launch options, content depots or the experience players get after installing it through the client.

Developers must also identify any common redistributables the game requires, such as DirectX or Visual C++, and make sure achievements are ready. If a game supports Steam Cloud, developers must confirm that cloud saves work. Store pages also need at least five screenshots categorized as actual gameplay. These checks are intended to make the submitted build and the game’s advertised features easier for reviewers to verify.

The changes do not amount to a general ban on games made with AI. They focus on whether the game launches correctly, whether its listed features work and whether its store page accurately represents the product.

AI-generated content is under scrutiny, but Valve did not blame it for the backlog

Steam already has a disclosure process for generative AI. Developers must describe AI-generated content that players see, hear or consume, including artwork, music, writing and localization. Valve says that AI tools used only to improve development efficiency are not the focus of that disclosure section. For content generated while a game is running, developers must also explain safeguards intended to prevent illegal output.

Destructoid cited an analysis by a Reddit user who tracked Steam’s AI disclosure labels. It found that 49.9% of games released in October 2026 disclosed some use of AI-generated content, compared with 26.4% a year earlier. That figure measures disclosure labels, not whether games are low quality. It also does not establish that AI submissions caused Valve’s review delays.

Valve’s November announcement did not mention AI as the reason for the backlog. It cited the rise in submissions and repeated reviews. Game Developer also noted that Valve had not directly attributed the longer schedule to any particular development trend. The distinction matters: AI use is a growing issue for storefronts, but the stated reason for the current review delays is the volume of submissions and the need to re-review builds.

Independent studios worry that delays will disrupt launch plans

A longer approval queue can be especially difficult for small studios. Launch dates are often coordinated with trailers, review copies, influencer coverage, discounts and wish-list campaigns. If a game is not approved on time, a developer may lose the promotional window built around its release.

The Verge and Kotaku reported that some developers had waited two or three weeks, with delays sometimes extending after a rejection or a request for clarification. One developer’s game, Wheel Make It, was delayed after a review issue involving a menu option that Valve could not access with a controller. The developer said the game used a shared keyboard for local co-op, which contributed to confusion about how to test the feature.

These cases show why the revised checklist may help developers avoid preventable problems. They do not prove that every delayed game was affected by the same issue or that AI-generated games were responsible for the delays.

Valve says more review-process changes are coming

The confirmed changes are that Steam build reviews can now take up to 12 business days, and developers are being asked to test games through Steam, check required redistributables and achievements, verify cloud saves when supported, and provide properly categorized gameplay screenshots. Valve described the changes as an initial step and said further improvements are planned.

It remains unclear when the submission queue will return to normal, whether the new checklist will materially reduce repeat reviews, and how much of the increase in submissions involves AI-generated content. For developers, the immediate practical change is to allow more time for review and test the Steam installation and launch experience before submitting. For players, Valve has not announced a new AI-game filter or a broad removal policy.
