Claude Code Rewrites Game-Clone Rule

Anthropic’s distinction is sensible in principle, but the fuzzy, model-enforced boundary remains difficult to audit and predict.

• –Named references should now guide genre-level inspiration, not trigger blanket refusals.
• –Renaming a faithful copy still does not bypass the restriction.
• –Independent testing found inconsistent behavior across similar prompts, highlighting the limits of prompt-based IP enforcement.
• –Ports, mods, licensed projects, and user-owned games remain unclear under the rule.
• –Shipping a meaningful behavior change without documenting it in release notes weakens developer trust.
