## Summary

Anthropic added instructions to Opus 5.5's system prompt that discourage Claude from recreating specific existing games, after an X post drew attention to the change. The article says the restriction covers only Claude, so users can route game-cloning tasks through other models, and it has also blocked legitimate original game development. It frames AI-driven cloning and console jailbreaks as a possible 'Napster moment' for the games industry, citing an indie studio that cancelled a public demo over fears of AI copying.

## Why it matters

The piece links Anthropic's new Claude Code restriction on game cloning to the wider disruption of the games industry, showing how the rule works in practice and where it falls short.
