Anthropic has introduced new restrictions to its Claude AI coding assistant to prevent users from recreating existing video games without permission. The move comes amid growing concerns among game developers that artificial intelligence tools are making it easier to copy games, potentially threatening the livelihoods of independent studios.
The restriction was introduced in Claude Code around October 27, 2026, and was subsequently confirmed by Anthropic’s technical staff member Addy Osmani.
Claude Code Introduces New Restrictions on Game Cloning
The updated instructions tell Claude Code to avoid recreating specific existing games, even when users rename them or describe them as original projects.
However, the restriction does not prevent users from developing original games, creating projects within established genres or building games using their own designs and assets.
Anthropic explained that the change was intended to prevent its AI tools from being used to infringe intellectual property rights. The company also indicated that it would continue refining its safeguards to maintain a balance between protecting developers and supporting legitimate creative work.
Game Developers Raise Concerns Over AI Clones
The restrictions come at a time when developers are increasingly worried about AI-generated copies of their games appearing online.
AI coding tools can analyse existing software and reproduce elements of its functionality, making it possible for users to create similar games with considerably less effort than traditional development methods.
Independent developers are particularly vulnerable because their games may have limited resources behind them and depend on the success of a single release.
Several studios have reportedly cancelled public demonstrations of upcoming games over fears that their content could be copied using AI tools before the original titles reach the market.
Developers have also raised concerns about the growing number of AI-generated game clones appearing on Steam, the popular PC gaming platform.
Restrictions Could Affect Legitimate Developers
While the new rule is intended to protect intellectual property, it has also raised concerns about legitimate development activities.
Some users have reported that Claude refuses to assist with reverse-engineering tasks involving their own projects. Such work can include analysing software behaviour, troubleshooting technical problems and adapting games for different platforms.
The distinction between legitimate development and unauthorised copying is not always straightforward. AI tools may struggle to determine whether a user owns the game or has permission to modify its software.
Anthropic has acknowledged the need to maintain an appropriate balance and has invited developers to report cases where legitimate projects are incorrectly blocked.
Will the New Restrictions Stop Game Cloning?
The effectiveness of the restrictions remains uncertain. Although Claude can refuse requests to recreate existing games, other AI models, including locally operated open-weight systems, may not have equivalent safeguards.
Users may also attempt to bypass restrictions through alternative prompts or development methods.
Anthropic’s decision nevertheless highlights the growing tension between AI-assisted software development and intellectual property protection. As generative AI becomes more capable, technology companies are facing increasing pressure to prevent misuse while ensuring that legitimate creators can continue using these tools.
Anthropic’s latest move could mark an important step towards protecting game developers from unauthorised AI-powered cloning. However, the restrictions are unlikely to eliminate the problem entirely, particularly as competing AI tools remain available.
