The Roman naturalist, Pliny the Elder, expressed an interest in perceptual illusion. The concept of virtual worlds significantly predates computers. Virtual worlds are not limited to games but, depending on the degree of immediacy presented, can encompass computer conferencing and text-based chatrooms. Media studies professor Edward Castronova used the term "synthetic worlds" to discuss individual virtual worlds, but this term has not been widely adopted. The form of communication used can substantially affect the experience of players in the game. Communication is usually textual, but real-time voice communication is also possible. Players create a character who travels between buildings, towns, and worlds to carry out business or leisure activities. Most MMORPGs have real-time actions and communication. Massively multiplayer online games depict a wide range of worlds, including those based on science fiction, the real world, super heroes, sports, horror, and historical milieus. Communication between users can range from text, graphical icons, visual gesture, sound, and rarely, forms using touch, voice command, and balance senses. Example rules are gravity, topography, locomotion, real-time actions, and communication. Such modeled worlds and their rules may draw from reality or fantasy worlds. The user accesses a computer-simulated world which presents perceptual stimuli to the user, who in turn can manipulate elements of the modeled world and thus experience a degree of presence. These avatars can be textual, graphical representations, or live video avatars with auditory and touch sensations.

This article is about general concept of a virtual world.
