Multimedia is a term used to describe a form of information delivery that utilizes multiple content forms as opposed to traditional forms of printed or hand-produced text and still graphics. Online means "on" one of the lines connected to the internet. Thus, multimedia online (MMO) games use text, audio, still images, animation, video, and interactivity.
Multimedia can be classified as linear and non-linear. Linear processes without any or little interaction with the viewer, such as with movies or books. Non-linear includes interaction, at least between the viewer and the game. Multiple forms of content are often not considered multimedia if they don’t contain at least audio or video. Thus, multimedia online allows multiple users to connect with the game in a network.
Multimedia online is increasingly becoming driven by people wanting to “experience” the game as much as possible with instant programming of the content based on the input of the players. Emerging technology involving taste and smell may increase this online experience.
Multimedia online games require currency to play. A player can buy the virtual currency from the specific game site or from an online exchange site where the currency can be used at various web sites. Just like real currency exchanges, the rates vary for online exchanges, depending on what the buyer’s system is, for example, Canadian or US dollars or Euros.
Gold buying is buying this virtual currency. Players use the currency and can earn currency in the games. When a player decides to leave the particular virtual world, the currency can be exchanged back to the player’s real currency. Numerous professional virtual currency exchange sites operate 24 hours a day, 7 days a week with competitive prices, instant delivery, and customer service.
