Abstract: A state system providing version agnostic centralized state management can use node graphs corresponding to virtual entities to maintain a world state among any version of a video game. As states to virtual entities change, corresponding nodes of the node graph are updated in response to the state change to account for and store the state change. As a data structure referencing, associating, and/or corresponding to virtual entities themselves, the node graph can facilitate centralized state management for a video game in a version agnostic manner. Additionally, the state system is also configured to validate node dependencies of a node graph when a corresponding change in state of a corresponding virtual entity occurs during gameplay, to avoid and/or prevent game state errors.
