Claude’s new rules against game cloning won’t stop the AI copying boom
System prompt restrictions highlight how AI labs attempt to limit copyright liability as coding assistants make cloning existing software increasingly trivial.
What happened
Anthropic updated the system prompt for Claude Code and its Claude Opus 5.5 model to prohibit the recreation of specific existing video games. Although the rule instructs the AI to build only original games rather than clones, observers note it is unlikely to halt the broader trend of AI-assisted game copying and porting.
