A Place to Play
Every day, people around the globe head to the same place to meet friends, test their mettle, and have fun. And it’s a place that doesn’t even exist.
World of Warcraft’s virtual realm boasts more people than Sweden. It earns $2 billion annually in subscriptions, outperforming many small nations. And this extraordinarily compelling, popular, profitable world is entirely a creation of software code.
Impact
The World that Conquered Earth
The landscape of World of Warcraft (WoW) may be virtual, but its impact is real.
The game helped transform the way we have fun...as well as the business of fun, influencing a computer game industry that earns more than $16 billion annually in the United States.
Offering rich imagery, engrossing experiences, and social connections, WoW raised the bar for gaming, building a universe of loyal fans—and imitators.

World of Warcraft debuted in November 2004, breaking all previous sales records in North America, Australia, and New Zealand. Today it enjoys a cult following by millions around the world. In 2015 WoW remained the world’s number one subscription‐based massively multiplayer online role-playing game (MMORPG).
Who's Playing?
Teenage boys binging on pizza and cola: that’s the gamer stereotype. But the image is outdated, thanks partly to World of Warcraft (WoW).
WoW's riveting visuals and social interaction helped broaden gaming’s appeal. As of 2011, nearly 45 percent of all players are female, and the average age is 37.

Former Maine senator Colleen Lachowicz, November 15, 2012
What happens in World of Warcraft stays in World of Warcraft...not if you’re running for the Maine Senate. Colleen Lachowicz, 2012 Senate hopeful, came under scrutiny for her “crude, vicious, and violent comments” made while playing WoW.
Virtual Becomes Real
Multiplayer games created online communities, which then became real-world communities.
World of Warcraft’s (WoW) unprecedented popularity and interaction revolutionized the way players relate to each other. Conventions, like BlizzCon, and gatherings of people who share a WoW“Guild,” as well as individual friendships (and romances), defy the stereotype of awkward loners.

Cosplay, from “costume play,” is a popular activity at BlizzCon. Convention goers create intricate costumes of their avatars or well-known characters, complete with complex props and accessories. The BlizzCon costume contest attracts hundreds and awards thousands of dollars in prizes.

With gaming servers located around the world, popular massively multiplayer online role-playing games (MMORPGs), like World of Warcraft, enable deployed soldiers to keep in touch with friends and stay up to date on the latest game play.
Not Just Fun and Games
“All work and no play” supposedly makes one dull. But what about all play and no work? Reports of gaming addiction fuel both fear-mongering hype...and legitimate worries.
“Gold farming,” in which people (typically in developing countries) play for long hours to collect and sell virtual currency and high-level characters, raises concerns about exploitation.

Gold farm in China
In World of Warcraft, gold is acquired through repetitive basic tasks. Human “gold farmers” are used to increase players' in-game currency, which is then sold for real money. Eighty percent of gold farmers reside in China and include children and labor camp prisoners.
Technology
Hardware and Software: The Power to Play
World of Warcraft may be a virtual realm, but the hardware and software it depends on is very real.
Sustaining the complex world of Azeroth, with its cavalcade of Goblins, Orcs, and Draenei, requires real-time coordination between local and remote systems. This complex interaction of software and hardware demands fast processors and video cards, as well as high speed Internet access.
The Right Game at The Right Time
Why did World of Warcraft (WoW) triumph? Because it was fun.
Its fantasy landscape was beautiful and its “quests” complex. WoWwas simple enough for beginners, yet let sophisticated users customize their experience. Plus, it debuted as prices were falling for powerful video cards and fast processors.

Quests allow players to earn money, gain experience, build reputation, and advance character storylines. They also allow for interaction and coordination between players, underscoring the rich narrative quality of WoW and other massively multiplayer online role-playing games (MMPORGs).
What’s Where?
That Orc attack seems to be on your computer. But World of Warcraft is actually choreographing a complex global ballet of hardware, software, and far-flung users.
Remote servers supply settings, game rules, non-player characters, and more. Each gamer’s computer, meanwhile, processes the visual, audio, and player information—so the game looks different to each player.

Massively Multiplayer Online Role-Playing Game (MMORPG) interaction (player’s perspective)
MMORPGs rely on real-time updates. When players execute a command, the command is recognized as code by the game engine. The game engine instantaneously coordinates a series of checks and updates before sound and visuals are relayed back to players’ displays.
Teamwork
Like making a Hollywood film, creating World of Warcraft is a collaborative effort.
Directors, producers, artists, writers, lighting consultants, composers, and others rely on a toolbox of animation, graphics, storyboard, music, and other software to bring the game and characters from their brains to our screens.

History
Old Game, New Medium
World of Warcraft is a brilliant example of inventive re-use.
The online game that debuted in 2004 evolved from Blizzard Entertainment’s Warcraft: Orcs & Humans, introduced a decade earlier as a single or dual player game for a standalone PC. The company adapted its successful Warcraft III: Reign of Chaos game engine to fit the online environment, bringing a proven product to a new medium and a global audience.

A Growing Community
Solitaire has its charms. But from the earliest days of computing, people have wanted to play with others.
Early games such as Maze War and Empire let users interact with people on their network. But not until the 1980s did games begin to span multiple networks, offering broader interaction.
Once Upon a Time...
World of Warcraft (WoW) tapped into a venerable tradition of fantasy computer and board games, many inspired by the Orc-infested lands in Tolkien’s Lord of the Rings.
Dungeons and Dragons, text-based computer games such as Oubliette and Adventure, and graphical games such as Ultima all paved the way for WoW.
