Multiple users claim Anthropic's Claude Code and/or Opus 5.5 now refuse to recreate specific existing games and some reverse-engineering tasks, including use of the Reverse Engineer Anything (REA) tool. Anthropic has made no official statement, and the rule text circulating online is unconfirmed.

Google has launched Playground, a browser-based platform that lets US adults create games from text prompts alone. It runs on Gemini, Nano Banana and Lyria, according to a Google spokesperson, and is free with higher weekly limits for Google One subscribers. Google and Unity also announced Unity Spark, a closed-beta tool for professional developers.

Anthropic's Claude Opus 5 can generate playable 3D games, including first-person shooters and Minecraft clones, from a single text prompt with zero external assets. Community tests claim it outperforms GPT-5.6 Sol and Kimi K3 in physics realism and mechanical complexity, though no standardized benchmark has confirmed the comparisons.

Epic Games released Unreal Engine 5.8 with an experimental Model Context Protocol plugin that allows developers to connect AI models including Claude and Gemini to the game engine. The company plans to make MCP integral to Unreal Engine 6, expected in late 2027.
