The author says the demo is driven by three.js-style generation, but imagines a future where Claude can do the same kind of work inside Unreal through MCP and MetaHumans, making it possible to churn out games quickly. The quoted post claims the demo used only custom code and no external assets, and says AI games are going to be amazing.
