Roblox embraces AI-generated games as Steam raises concerns about quality

In its Q3 2026 shareholder letter, Roblox said its AI prompt-to-game tool Build, launched in July, has been used by over 500,000 users to publish more than 70,000 games, and that over 80% of its top 100 games by hours engaged used AI tools in the past month. Roblox framed the resulting "explosion of content" as an advantage built on social distribution, while Valve has acknowledged AI-generated games and clones flooding Steam as a problem it has not yet resolved. Roblox also described initiatives including Roblox Everywhere and a Universal Player that uses AI to import existing games into its cloud platform, with a stated goal of capturing 10% of the global gaming market.
