Per a screenshot of Claude Code on Twitter, the full rule is: “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.”
It's so broadly worded, the LLM could refuse just about any retro or vintage related decomp. Pong (1972) and Space Invaders (1978) are both "specific existing games." Seems like dropping a grenade when a scalpel would have sufficed. The "Do" and "Don't" also seem bizarrely inverted. Using actual existing game assets or code is copyright infringement. Re-implementing an existing game without original assets or code is generally legal.
