Claude’s new rules against game cloning won’t stop the AI copying boom
Claude's new anti-cloning rules target AI copying amid a broader copying boom.
Context
What happened: Anthropic added a system prompt rule to Claude Code telling the model to build original games but not recreate specific existing games, even if renamed or called original.
Key numbers: Rule noted around October 27; verified in Claude Code version 2.1.314, released October 30.
Why it matters: The move could shield Anthropic from some liability, but the article says it is unlikely to slow the wave of AI-assisted game porting and copying.
