Anthropic has added a rule to Claude's instructions asking it to build original games, games in a genre or games based on the user's own designs and assets, but not a recreation of a specific existing game, even if renamed, Engadget reports. A member of the company's technical staff explained that using Claude to infringe intellectual property breaks its usage policy and that the rule will be refined. The change follows a wave of big commercial games decompiled with AI help and released as browser versions. Anthropic has already faced major copyright disputes.
What it means: The change shows how model providers are trying to limit their legal exposure without losing users who make legitimate content. AI coding tools have become capable enough to reproduce entire games, and publishers are pushing back. The line being drawn, genre allowed, specific work not allowed, is sensible but hard to apply, because a game can be heavily inspired by another without being a copy. For Greek game studios and teams using AI in development, the practical message is twofold. First, tools may refuse requests that resemble well-known titles, so specifications should describe mechanics rather than names of works. Second, responsibility for originality stays with the team, whatever the tool allows. The same concern applies beyond games: apps, websites or designs that copy protected works with AI help expose a company to claims. A short internal guideline on how to reference third-party works in prompts and specifications is useful, low-cost protection for any team.
