Techniques for implementing inter real-world and virtual world subject matter interchange are described. Particularly, the techniques leverage an extension of a game application to access one or more objects in the real-world that are mapped as at least one virtual element on the virtual world. The objects in the real-world may include a business or an entity that can be represented by at least one virtual element in the virtual world. In one example, an installation of the extension may allow the objects in the real-world to be mapped as virtual elements on the virtual world. Based upon a player's interaction with the one or more virtual elements, an event handler is triggered to expose at least one application program interface (API) of the corresponding mapped objects. A subsequent execution of the event handler may implement the inter real-world and virtual world subject matter interchange.
