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.
Gameplay of World of Warcraft
In a change from the previous "Warcraft" games produced by Blizzard, "World of Warcraft" is a massively multiplayer online role-playing game (MMORPG) where thousands of players can interact with each other. Despite this change, the game draws many similarities with its predecessors. These include using the same setting of the world of Azeroth as well as following a similar art direction. In common with many MMORPGs, "World of Warcraft" requires players to pay for a subscription, usually either by credit card or by buying a card from a retailer to redeem for a predetermined amount of subscription time; in addition, game time may be acquired from using in-game gold to buy a WoW Token.
