Anthropic's Claude Code now blocks video game clones

By PulseAugur Editorial · [4 sources] ·

Anthropic has implemented a new restriction in Claude Code's Opus 5.5 model, preventing it from recreating existing video games. This change, added to the system prompt without a formal announcement, blocks requests to clone specific titles, even if renamed or presented as original. While the policy aims to prevent intellectual property infringement and has been confirmed by Anthropic, it has led to unexpected refusals for developers, including those working on commissioned projects. The restriction allows for the creation of original games, genre-based games, and projects using user-provided designs and assets, but specifically targets direct recreations of known commercial titles. AI

IMPACT Developers using Claude Code for game development must now ensure their projects are original or genre-based, as direct recreations of existing titles are blocked.

RANK_REASON This is a server-side configuration change to an existing tool, not a new model release or significant policy shift.
