World of Warcraft
"World of Warcraft" was first announced by Blizzard at the ECTS trade show in September 2001. Released in 2004, development of the game took roughly 4–5 years, including extensive testing. The 3D graphics in "World of Warcraft" use elements of the proprietary graphics engine originally used in "Warcraft III". The game was designed to be an open environment where players are allowed to do what they please. Quests are optional and were designed to help guide players, allow character development, and to spread characters across different zones to try to avoid what developers called "player collision". The game interface allows players to customize appearance and controls, and to install add-ons and other modifications.
World of Warcraft
"World of Warcraft" takes place in a 3D representation of the "Warcraft" universe that players can interact with through their characters. The game world initially consisted of the two continents in Azeroth: Kalimdor and the Eastern Kingdoms. Four separate expansions later added to the game's playable area the realms of Outland and Draenor and the continents of Northrend and Pandaria. As a player explores new locations, different routes and means of transportation become available. Players can access "flight masters" in newly discovered locations to fly to previously discovered locations in other parts of the world. Players can also use boats, zeppelins, or portals to move from one continent to another. Although the game world remains relatively similar from day to day, seasonal events reflecting real world events, such as Halloween, Christmas, Children's Week, Easter, and Midsummer have been represented in the game world. Locations also have variable weather including, among other things, rain, snow, and dust storms.
