Anthropic Tightens Claude Code to Block AI Video‑Game Clones

Anthropic has revised the system prompt for its Claude Code model to prevent it from reproducing existing video games.

The update follows a surge of AI‑generated “clones” that re‑create classic titles from source code or asset dumps. Those decompilations and ports have crowded retro‑gaming forums, raising concerns about intellectual‑property infringement and the loss of original creative work.

While the new prompt bars the model from recreating copyrighted games, it still permits users to design original titles. Developers can continue to experiment with game mechanics, art styles, and narratives, but the tool will refuse to generate code that mirrors a specific existing game.

The move signals Anthropic’s intent to balance innovation with legal and ethical boundaries. It remains to be seen how the community will respond and whether other AI platforms will adopt similar safeguards.
