Anthropic is blocking its Claude Code coding assistant from recreating existing video games. Two sentences were added to the system prompt for Opus 5.5. The rule violates Anthropic's usage policy for IP infringement and applies even to renamed or rebranded clones. Users can still build their own games and projects with custom assets but some report issues with original work. This follows a wave of AI-generated browser ports of titles like Halo and GTA Vice City.
