Why world model teams pay for gameplay with inputs attached: actions are the scarce half

A Reddit analysis argues the real bottleneck for world models is paired screen-plus-input data: video alone shows what happened, while the action that explains it is scarce. Examples: OpenAI's Minecraft work turned 2,000 labeled hours into 70,000 auto-labeled ones; Microsoft kept seven years of controller inputs for Muse; NVIDIA read inputs from streamers' overlays. Most such data lacks 'other minds' — intent and collaboration context. The author built a game where humans and AI models fight the same wars with every move logged, and finds behavior data (promises, betrayals, clutch decisions) more interesting than physics.
