A text driven adventure game that affords players the use of Natural Language as the "controller".
The player(s) interact with the World through natural language. An LLM maps player intent into the functional procedures provided by the World Interface. The game state is maintained through the World State.
The World is defined as the union set of all Entities each having A) Capabilities & B) State. The World Interface is therefore defined as the union set of all Entity Capabilities. Likewise, the World State is defined as the union set of all Entity State. A Capability defines some possible A) Observation, B) Action or C) Reaction an Entity is capable of. A State is some collection of data representing the current condition of the Entity.
The World is distributed, there is no concept of omnipotence from within the boundary of the world. Entities form causal relationships with one another in a concurrent manner; these relationships are propogated to neighboring peers. Any grouping of Entities whose causal graph is fully contained is called a microcosm. Causal events do not propogate beyond microcosms; microcosms are independent of each other.
Any singular programatic object that contributes to the Game World is an Entity. Entities are either active (Agents) or passive (Fixtures). Entities can apply actions to the world, recieve re/actions from the world & observe the world. What delineates an Agent from a Fixture is it's Agency, any entity with the intrinsic capability to take action is considered to have Agency. Likewise, any Entity that cannot act without first receiving input from the world has no Agency & is therefore a Fixture.
Note
This definitions of Agency is intended to be pragmatic, not philosophical, aimed at classifying & driving implementation. Generally speaking, these definitions apply within the context of the World. IE. A user injecting player movement into an entity constitutes Agency since, from the perspective of other world entities, that Agent is able to move itself without input from the world. An Agent need not be "Intelligent".
When an Entity observes the World, the World State of the corresponding microcosm "collapses" & all causal relationships are resolved; in otherwords, within the scope of a microcosm, all state caches are replicated.
