Anthropic has changed Claude Code’s instructions to discourage recreations of specific existing games, while continuing to allow original game projects, according to GamesRadar’s November 2 report. The distinction could matter for developers using the tool to make games, as well as fan projects seeking to reproduce familiar titles on PC.
GamesRadar cites Anthropic technical staff member Addy Osmani, who said two sentences had been added to Claude Code’s prompt on Opus 5.5. He attributed the change to the company’s policy against using Claude to infringe intellectual property.
Original designs remain permitted
The instructions described in the report allow original games, projects within established genres, and games using a user’s own designs and assets. They also direct the tool against recreating an identifiable existing game, including when that recreation has been renamed or presented as original.
That leaves room for developers to work within familiar categories without reproducing a particular title. Osmani also invited users to flag cases where Claude rejects work that belongs to them, acknowledging the possibility that the restriction could catch legitimate projects.
Impact on fan projects remains uncertain
GamesRadar places the change alongside AI-assisted recreations and ports involving Bloodborne and several Nintendo games. It reports that a Bloodborne PC project attracted attention last month and credited Claude across much of its development.
Those examples explain the gaming relevance, but they do not establish that the revised instructions will reliably block comparable projects. The report leaves enforcement effectiveness unresolved.
For PC and console gaming communities, the practical question is how consistently Claude will distinguish an original project from a recreation. The announced prompt change establishes an intended boundary; its effect on fan development and storefront copycats remains uncertain.
