Anthropic Updates Claude Code to Block Direct Video Game Clones

Anthropic has revised the system prompt for its Claude Code AI to prohibit the creation of direct copies of existing video games. The update follows a surge of AI‑generated decompilations, recompilations, and ports that have flooded the retro gaming scene. While the tool remains available for building original titles, new prompt language now instructs users to “build original games, games in a genre, and games from the user’s own designs and assets” and explicitly forbids recreations of specific existing games. The change was first reported by Tom’s Hardware and confirmed by a screenshot posted on X last week, which highlighted the two added sentences. Anthropic’s move aims to curb copyright‑infringing use of its AI while preserving creative development.
