Direct answer
Gameplay data becomes world-model training data when controls, observations, state, and outcomes are synchronized at episode level. Video alone is only one stream.
Games expose controlled dynamics at scale
Games provide repeatable environments, precise event boundaries, broad action spaces, and measurable outcomes. Engine access can expose state that would be expensive or impossible to recover from pixels, including object transforms, collision events, inventories, and reward logic.
The same game can still produce very different datasets. Spectator footage, livestream video, bot matches, player recordings, and instrumented private sessions carry different labels, rights, privacy exposure, and reproducibility.
Capture the control surface
Record keys, buttons, pointer deltas, analog axes, menu context, and control remapping. Preserve the raw input alongside a normalized action representation so a buyer can audit how labels were transformed.
Menu interactions, pauses, replays, loading screens, and camera transitions need explicit states. Treating them as ordinary play can corrupt temporal learning and inflate nominal hours.
Engine telemetry is powerful and dangerous
Ground-truth state can support dynamics learning, object tracking, privileged training, and evaluation. It also creates version dependencies. Field meanings can change across patches, mods, maps, and server configurations.
Ship a field dictionary with units, coordinate frames, nullability, update rate, source system, and version. Keep unavailable state explicit rather than filling it with plausible defaults.
Rights determine the commercial product
Owning a capture pipeline does not automatically clear a game's audiovisual content. Commercial releases need documented authority covering capture, training, redistribution, customer use, and generated outputs where relevant.
Public research datasets remain useful reference material, but their listing on a commercial catalog must not imply resale rights. Separate first-party inventory from external references in navigation, labels, schema, and calls to action.
