Claude begins blocking requests to clone existing video games

New restrictions on game clones

The AI model Claude from Anthropic is currently declining prompts that ask to build replicas of current video games. As reported by ProPakistani, these refusals occur even when people try to hide the source by giving the project a different name or claiming it is a unique creation. This behavior suggests a specific policy aimed at stopping the generation of clones.

Users have noted that the AI is instructed to build original games, games within a specific genre, or projects based on a user's own assets. However, it is now actively avoiding the construction of a recreation of a specific, well-known game. This shift has been observed primarily through the company's coding assistant and its Opus 5.5 version.

While Anthropic has not released an official statement, the change has caused a wave of complaints on GitHub. Developers have reported that their requests are being refused halfway through development or when trying to copy a specific game mechanic. These refusals are occurring despite the fact that the users are not necessarily trying to pirate a specific title.

Impact on legitimate technical work

The new restrictions are causing significant friction for users who perform legitimate reverse-engineering. Reverse-engineering is the process of taking apart existing software to understand how it functions. Many users on Reddit report that Claude now refuses to help with tasks like analyzing a simple Windows crash dump or removing junk software from a Samsung TV.

Some developers have also found that the tool is blocking work related to anti-cheat development and security reviews for their own games. These users report that the AI's safeguards are being triggered by these requests. This may be linked to Anthropic’s Cyber Verification Program, which limits access to advanced cybersecurity capabilities to specific organizations.

Not all users agree that the restrictions are as broad as they seem. Some argue that the changes only stop lazy cloning, such as asking the AI to remake a famous game in a different style. These users suggest that more complex tasks like modding or decompilation work might still be permitted by the model.

Legal and industry motivations

The likely reason for these changes is legal protection for Anthropic. AI companies face a high risk of litigation from software and game studios if their tools are used to duplicate or break products. There has been a growing concern regarding AI-made clones of popular software suites like Microsoft Office or Adobe applications.

Small game studios are also facing unique challenges in this environment. Recent events at Steam Next Fest showed a high volume of AI-made games that were copied from existing titles. Some developers have even been targeted by extortion scams where individuals threaten to clone a game demo into a full game before it can be released.

Anthropic is not the only company taking these steps to mitigate risk. OpenAI recently deactivated a user account for attempting to clean up a television's software. These actions suggest a broader trend where AI providers are tightening the guardrails around what their models can do with existing software.

What this means for users

If you are using Claude to build games, your original ideas and genre-based projects should still be allowed. However, any request that resembles a copy of a famous game, even with a different name, will likely be refused. You should be aware that the AI is becoming more sensitive to prompts that involve existing intellectual property.

For developers, freelancers, or students, this means you may see more refusals for debugging or security testing. Even if your work is harmless, the AI's safeguards might flag the request as a violation of its new rules. It is important to test your usual workflows before relying on the tool for client projects.

Many users are already suggesting alternatives for these specific types of technical tasks. This includes using Chinese models, open-weight models, or models that are run locally on your own hardware. These options may provide more freedom for reverse-engineering and deep software analysis without the same level of restriction.
