An exemplary virtual reality media content access control system (“system”) selectively provides access to virtual reality media content for experiencing by a user of a media player client device (“client device”). In certain examples, the system detects a request from the client device to access an immersive virtual reality world that includes a virtual object assigned an access permissions profile, determines an access key and a device key associated with the request, validates the access key and the device key associated with the request, determines metadata associated with the access key, and selectively provides, based on the access permissions profile for the virtual object and on at least one of the device key associated with the request and the metadata associated with the access key, access to the virtual object for experiencing by the user of the client device as part of the immersive virtual reality world.
