Claude refused requests to clone existing games and software but continued helping with game modding and reverse engineering in PCMag's testing. The review examined how Anthropic's recently added rules for Opus 5.5 affect coding work, including requests to recreate products with fresh code and assets.

The reviewer used Claude to decompile Valheim's latest update and several mods for maintenance and development projects. Requests to copy games were refused even without reusing their assets or code. Anthropic's rules allow original games and projects built from users' own designs and assets, though the review also cited a user whose personal board game adaptation was rejected.
