Anthropic has changed how Claude handles game requests. Newly added instructions, first found by an X user, say Claude should build original games, genre-style games, and games from a user’s own designs and assets. It should not recreate a specific existing game, even if the game is renamed or described as original.
Addy Osmani, who works on Anthropic’s technical staff, confirmed the update on X. He explained that the goal is to keep Claude from recreating someone else’s specific game, because infringing IP with Claude is prohibited by the usage policy. He said original games, genre games, and games using a person’s own designs and assets should remain unaffected, and that Anthropic plans to keep refining the approach.
The update follows a rise in AAA games being decompiled with AI and released as browser-playable versions. Fan-made, vibe-coded versions of Halo: Combat Evolved, Call of Duty: Modern Warfare 2, and Grand Theft Auto V have all appeared recently.
This isn’t Anthropic’s first brush with intellectual property disputes. Last year, the company agreed to a record $1.5 billion settlement in a class action brought by roughly 500,000 authors, who accused it of using copyrighted works to train its AI models. The estate of Elvis Presley has since sued Anthropic on similar grounds.
