The gaming industry is currently grappling with an influx of artificial intelligence-generated titles that have saturated digital platforms. Events like Steam Next Fest recently struggled as AI games overwhelmed the showcase, making it difficult for players to discover genuine indie projects. Data from itch.io indicates that the number of game pages created has doubled in the last two months, a trend attributed to the rising popularity of "vibe coding" and tools like Claude. Beyond original AI creations, there is growing concern regarding AI-generated remakes and copycats of established games.
To address this issue, Anthropic implemented a significant update to its guidelines on October 30. An X user first noticed the change in Claude Code's rules, which now state: "Do build original games, games in a genre, and games from the user's own designs and assets. Don't build a recreation of a specific existing game, even if it is renamed or called original." An Anthropic spokesperson confirmed the update to Game Developer on the same day. Addy Osmani, a member of technical staff at Anthropic, explained on X that two sentences were added to the prompt for Opus 5.5 to steer the model away from recreating specific games, as infringing on intellectual property violates their usage policy.
The new guidelines are designed to prevent users from bypassing restrictions through dialogue manipulation. Consequently, Claude will only generate games based on designs and assets provided by the user. While the specific criteria the AI uses to distinguish between original materials and copied assets remain undisclosed, users who believe they have been wrongfully flagged can contact staff members to resolve the issue. The update aims to ensure that original games, genre-based projects, and those built from user-owned assets continue to function without restriction.
This move has been welcomed by independent developers who fear having their work stolen by "vibe-coders." Several small studios have already taken preemptive measures, canceling public playtests in favor of controlled private environments. For instance, Alliance Arts and Who You withdrew their game, Drunken Goddess Reflux, from the October Steam Next Fest despite having 25,000 wishlists on Steam, to prevent dishonest players from copying their work. Similarly, Digital Sun canceled the public playtest for ReVamp, opting instead for a controlled test on Discord.
While Anthropic's update represents a positive step for developers, challenges remain. Safety limits on large language models can still be circumvented by determined users. Additionally, "vibe-coders" may simply shift to open-weight models that are free to use and have safety guardrails that are easier to remove.
