Claude Will No Longer Rebuild Your Favorite Video Game for You

Anthropic has drawn a clearer line around what its AI assistant Claude can do with video games, blocking it from recreating existing titles even when users try to disguise the copy.

The change was first spotted by a user on X in the internal instructions for Claude Code, and was then confirmed by Anthropic technical staff member Addy Osmani. The new instruction reads: 'Do build original games, games in a genre, and games from the user's own designs and assets. Do not build a recreation of a specific existing game, even if it is renamed or called original.'

In other words, renaming a well-known game or describing it as an original idea will not get around the rule. Anthropic's explanation, as reported by Engadget, is that using Claude to infringe intellectual property violates its usage policy, and the added sentences are meant to steer the model away from copying someone else's specific game.

Original work is still allowed. Users can build a brand-new game, work within an established genre, or build from their own designs and assets, and Anthropic says it will keep refining the balance between creative freedom and compliance.

The move lands as AI coding tools make it easier than ever to spin up playable remakes, raising fresh questions for developers about where homage ends and infringement begins. For now, Anthropic's answer is explicit: inspiration is fine, a recreation is not.
