Valve Updates Steam Review Guidelines Amid AI-Driven Game Submission Surge

Valve has updated its Steam review guidelines and checklists following a surge in game submissions driven by the AI era, which has caused review delays of up to 12 working days. The surge in AI-generated content is straining platform moderation pipelines, prompting major distribution platforms like Steam to enforce stricter pre-submission criteria to manage bottlenecks. Developers must now launch their game through the Steam client for at least 5 minutes, ensure achievements are ready, and confirm redistributables like DirectX before submission to avoid repetitive re-reviews.
