In addition to my earlier post where I focussed on 'Entertainment':
'Media' is a Latin word meaning an agency, means, or instrument. Videogames, in terms of sight, sound, and space, can mimic or expand upon things that don't exist on a screen. For instance, a videogame can contain a mock newspaper if it so wishes, or, in online mode, can contain regular new information to its players, one of the functions of a newspaper. A videogame can contain a mock TV show, such as in Remedy's or Rockstar's work, often contains full musical scores such as at a concert. A videogame can allow you to interact with a representation of a museum or library, real or otherwise. A videogame can be like a tasting menu of all other media and entertainment, or can focus on just one or two aspects and become a way of experiencing one media in a comprehensive / indepth way.
