Abstract: A system in which players participate as characters in a virtual game world via game clients executing on client devices. An observer mode is provided that enables users to navigate in the game world without requiring a game client so that a user can navigate the game world while not actively playing the game. When a user accesses the game in observer mode, a view of the game world is rendered from the viewpoint of an observer's character; the observer's character may not correspond to a character in the game and the observer's character may not be visible to the players in the game. The rendered view of the game world is streamed to a viewing application on a personal device. Navigation inputs allow the observer's character to move freely within the game world.

Abstract: A system in which players participate as characters in a virtual game world via game clients executing on client devices and communicate via an in-game communications channel. A messaging service is provided that enables active players to communicate with non-players via messaging platform(s). A player may send a message to another person via an in-game communications channel; upon detecting that the person is not active in the game, the service maps the person's identity to one or more messaging platform endpoints, tags the source of the message with the sending player's in-game identity, and forwards the message to the person via the messaging platform(s). The person may respond to the message via the messaging platform(s). The identities of the active player may be obfuscated so that a player's personal contact information is not exposed.

Abstract: A game system in which virtual representations of real-world, physical objects may be designed or modified by game players within a virtual game universe. Real-world physical interactions of the virtual objects may be simulated by a game engine during game play within the game universe. Performance data may be collected for the virtual objects that simulates real-world performance data for corresponding physical objects. The performance data for the virtual objects may, for example, be used in evaluating performance of modifications to a physical object, or for comparing performance of two or more physical objects. Production or manufacturing decisions for respective physical objects may be made at least in part based on the performance data collected for the virtual representations of the objects.
