Anthropic has limited Claude Code from recreating specific existing video games. Independent developers have also reported refusals involving projects they say are legitimate, including commissioned game-related work that they claim should not fall under the restriction.
Users first spotted the restriction around 27 October in a prompt used by Claude Code when running Anthropic's Claude Opus 5.5 AI model. It tells the tool not to recreate a specific existing game, even if the project is renamed or described as original. Anthropic says the instruction is intended to prevent infringement of intellectual property, while original games, genre-based projects and work using a user's own designs and assets should remain supported.
