Key points
- Anthropic added two prompt sentences to Claude Code’s Opus 5.5 to block recreations of specific existing games
- Original games based on user designs remain permitted, but recreations of published titles are now prohibited
- Rule follows viral AI-assisted game ports like *Bloodborne* and *Mario Kart Wii* clones flooding Steam
