Why am I seeing this Ranked on corroboration — 2 independent outlets
2 independent outlets carried this — Tom's Hardware and TechPowerUp. Agreement across newsrooms that do not share an owner is the strongest thing we can measure, so it carries the most weight.
StandardStandard, because two or more independent orgs carry it, the subject was identified from the text, and it scores 0.50 against a bar of 0.50.

| Freshness | 0.20 | 0.72 | +0.143 29% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.
Anthropic's Claude model, specifically the Opus 5.5 version, has begun blocking requests related to video game recreation and reverse engineering. Users report that the AI refuses tasks ranging from cloning existing games to decompiling code, even when the work involves non-malicious technical analysis or personal projects.
The restriction stems from a new rule in Claude's guidelines that prohibits recreating specific existing games while permitting original games and genre-based projects. Anthropic appears to have implemented this policy in response to increased activity around game cloning, including fan-made ports and recreations of commercial titles like Fortnite and Fallout.
The enforcement has created unintended consequences. Developers report that Claude now refuses to help replicate their own previous work when building similar mechanics elsewhere in a project. Multiple issues have been filed on Claude's GitHub repository documenting cases where the filter blocks legitimate development tasks alongside the intended restrictions.
What happened
AI game cloning, reverse-engineering, and decompiling have all become increasingly popular of late, with a cottage industry of gaming projects popping up almost overnight, including everything from controversial Fortnite and Fallout clones to fan-made console ports. Now, it seems as though Anthropic may have had enough of the bad press and potential pressure from gaming industry giants, with some users reporting (via Tom's Hardware ) that Claude will no longer recreate game mechanics or existing games. One X user flagged a new rule in Claude that could potentially be the source of the restriction, which states "Do build original games, games in a genre, and games from the user's own designs and assets.
