Alternate Reality Game (ARG)
A game based in the real world but which has a fictitious plot or an alternative reality. Unlike computer games, which are controlled by computer programs, it is actively controlled by its designers. An ARG usually involves a variety of media and may include the use of real locations. All websites, phone numbers, email addresses, characters, etc in the game are “real” for game purposes and can be interacted with. An ARG does not require the players to assume fictional identities or to role play beyond accepting the alternative reality of the game for playing purposes.
