Anthropic Tightens Claude Usage Boundaries, Prohibits Replicating Existing Games
Anthropic has updated Claude's usage rules, explicitly disallowing the construction of a replica of a specific existing game, even if it is renamed or called original. Some users report that Claude has therefore refused to replicate work the developers themselves completed earlier, and the scope of impact extends beyond games, including refusing to invoke the "Reverse Engineer Anything" capability. The clause is believed to be intended to avoid copyright and legal risks, but it has already sparked a large number of new issues on Claude's GitHub page.

Now it seems Anthropic has had enough of the negative publicity, and may also be under pressure from gaming industry giants. Some users report that Claude is no longer willing to replicate game mechanics or recreate existing games, with Tom's Hardware first reporting on the situation.
A user on X pointed out a new clause in Claude's rules, believing it may be the source of the above restrictions. The clause states: "You may build original games, games within a genre, and games based on the user's own designs and assets. Do not build a replica of a specific existing game, even if it is renamed or called original." The intent of this new rule may be to prevent copyright infringement and avoid legal risks Anthropic might face, but the actual effect has been a flood of new issues on Claude's GitHub page. There are reports that Claude even refuses to replicate work the developer themselves completed early in a project, simply because subsequent development requires similar mechanics.
On platforms such as Reddit, users have also reported that the impact of this issue extends beyond the gaming field. Reports mention that Claude refuses to invoke the popular "Reverse Engineer Anything" capability, which was previously used for a variety of purposes: from cracking vendor lock-in on smart TVs, to adding features to car infotainment systems, and even including recompiling video games to run on other platforms.
