Anthropic orders AI tool Claude to stop remaking video games
Anthropic confirmed a prompt change for Opus 5.5 while a developer reported refusals affecting commissioned game modules.
TL;DR
- Anthropic added instructions intended to steer Claude Code on Opus 5.5 away from recreating specific existing games.
- The company said original games, genre-based games and projects using users’ own designs and assets should still work.
- A developer reported refusals on commissioned digital board-game modules, but the reach and consistency of the restriction remain unclear.
Anthropic added two sentences to the Claude Code prompt for Opus 5.5 intended to steer it away from recreating someone else’s specific game, Game Developer reported. An Anthropic spokesperson pointed the publication to an explanation by technical staff member Addy Osmani. [1]
Osmani said original games, genre games and games built from users’ own designs and assets were meant to remain possible. He said Anthropic would continue to adjust the approach. [1]
In a separate GitHub issue, developer lerugray reported refusals affecting commissioned digital board-game modules for individual clients. The developer corrected an earlier description and said the work was not publisher-licensed. [2]
The developer said the refusals began after asking Claude whether the rule affected the work. The scope and consistency of refusals, including for authorized projects, remain unverified. [1] [2]
Why it matters
A coding agent’s content rules can affect both rights holders and developers whose projects resemble existing games. How the boundary is applied determines the practical effect of the policy on development work.
Editor's note
Anthropic confirmed the prompt change, but the reported professional-work refusal is one developer’s account. The developer corrected an earlier claim that the work was publisher-licensed.
