Discovered inside Claude: Users will no longer be able to create them even if they want to
AI giant Anthropic has changed its policies. The new rule detected in Claude Code version 2.1.314 prevents the AI from copying existing video games from scratch, even if the names are changed.
With the widespread adoption of artificial intelligence (AI) models, their use cases have also expanded. Models like Claude can now generate videos, games, websites, and complex graphics. As concerns grow, Anthropic implemented a change for its Claude model.
The new rule detected in Claude Code version 2.1.314 prevents the artificial intelligence (AI) from copying existing video games from scratch, even if their names are changed. What does this mean?
RESTRICTION INTRODUCED TO CLAUDE
Claude's developer Anthropic added a new restriction to the usage instructions of its artificial intelligence (AI) model Claude. According to the rule detected in application files, Claude will not accept requests to recreate existing video games from scratch. Changing the game's name or presenting it under a different title will not be enough to bypass this restriction.
The restriction emerged when the code of Claude Code version 2.1.314 was examined. The company did not publish an official notice regarding the scope and enforcement area of the rule, which was uncovered after experienced users noticed it.
What do the new rules allow and prohibit for developers?
The instructions added to the software divide Claude's boundaries in game development into two categories. The artificial intelligence (AI) continues to support users' independent projects based on original ideas or coding processes for a specific game genre. However, prompts requesting an exact copy of a known and commercially available game are blocked by the system.
There is no full clarity on which models the restriction is technically applied to and to what extent. According to the shared information, the rule can be enabled independently for the Opus 5.5 model, but whether the same restriction covers other models in the application remains unclear.
Tested on Pokemon Diamond
The game Pokemon Diamond was used in trials to test the boundaries of the rule. Claude declined the prompt asking to recreate the game directly from scratch, citing its new instructions. In contrast, a different stance was taken during the technical code conversion processes of the same project.
| Operation Type | Claude Response | Scope of Operation |
|---|---|---|
| Cloning the Game from Scratch | Rejected | Request to directly reproduce existing game mechanics |
| Source Code Decompilation | Accepted | Translating decompiled code into readable C language |
| Code Compilation | Accepted | Generating executable data from user-owned files |
| Windows Porting | Accepted | Compiling the game to run on the Windows operating system |
The model continued to assist users with source code conversion and preparing development tools. Decompiling the code and porting it to the Windows platform was approved, as it was not classified as cloning from scratch.
Are platform porting efforts at risk?
Developers have long used artificial intelligence (AI) in projects to port games to different hardware. Running Nintendo Switch games on macOS systems or porting The Legend of Zelda: The Wind Waker HD to PC are among these projects.
Claude's new behavioral rule does not directly prohibit such porting processes. However, the artificial intelligence (AI) may perceive porting commands as a copying attempt. Anthropic has not released a detailed framework regarding the criteria the system will use to make this distinction.
