Traditionally, certain areas have been hotbeds of PvP action. These include the zones of Arathi Highlands and Stranglethorn Vale. However, in mid-2006, the concept of “world PvP” was expanded with the introduction of zone-wide PvP objectives. An early proof of concept for world PvP objectives is located in Silithus, where players are tasked to collect samples of a dust-like object called “Silithyst” and turn it in to their respective faction’s camp. A tally of how much Sillythyst each side has collected is visible to anyone present in the zone, and when one side reaches 200 samples, players of that faction gain a temporary buff and their side’s counter resets.[1]

The Eastern Plaguelands was another testing ground for world PvP objectives. The zone is home to four towers, which can be “captured” by standing on one for a brief time. When one side simultaneously controls all four towers, players on that side gain a beneficial buff, but upon losing control of any of the towers, the buff disappears. The PvP objectives in Silithus and the Eastern Plaguelands were released in patch 1.12 of the game.[2] Blizzard opted to promote the Plaguelands PvP release more heavily, however.[3]

The release of World of Warcraft: The Burning Crusade, the first expansion to WoW, made world PvP objectives a significant part of the game. For instance, the first zone of Outland, Hellfire Peninsula, contains a situation similar to that of the Eastern Plaguelands: three towers in the center of the zone may be “captured” by standing on them for a period of time, and controlling all three towers provides certain benefits. World PvP objectives exist in most zones of Outland.

In addition to playing the game itself and conversing on discussion forums provided by Blizzard, World of Warcraft players often participate in the World of Warcraft virtual community in creative ways, including fan artwork[37] and comic strip style storytelling.[38] Blizzard furthers this community by offering in-game and out-of-game prizes, as well as highlighting community events and occurrences. Blizzard has also provided incentives for introducing new members to World of Warcraft. In late October 2005 each subscribed player received a 10-day free pass[39] which they suggested be employed as seasonal gifts that could either be used by the current player or given to a friend. These passes would generate a free month’s usage if the guest player purchased a full account.

There are various memes, including “Face Melting,”[40] a reference to a very long thread on the priest forums on the World of Warcraft website that consisted of players saying, “You will melt faces as a Shadow Priest in PvP” in different ways. This is because the icon for Mind Flay, a powerful skill used heavily by Shadow Priests, looks like a melting face. Another popular phenomenon in the community are machinima videos such as the one[41] starring a player named Leeroy Jenkins, showing him and his guild in a funny encounter. Leeroy’s popularity inspired more videos and tributes in other games, and he was even part of a clue on the November 16, 2005 episode of the TV game show College Jeopardy!.[42] These memes gain notoriety through postings on the World of Warcraft Forums.[43]

As of August 2005, the Dark Iron server has been home to the guilds of web-comic creators Scott Kurtz (PvP) and Mike Krahulik and Jerry Holkins (Penny Arcade). Kurtz created Panda Attack and Djörk on the Horde side, while Holkins and Krahulik initiated a series of guilds that is now known as the Penny Arcade Alliance. This event is referred to as the Comic Guild Wars, and has created healthy competition between the authors, to the extent of dedicating some of their strips to the subject. Tim Buckley of Ctrl+Alt+Del and the creators of Holy Bibble have also joined in on making guilds for Dark Iron players.

There are two types of characters in the game: Player Characters (PC) and Non-Player Characters (NPCs). A Player Character is a player’s avatar in the world of Azeroth. The color of a PC’s name tag can vary from white, green, yellow or red depending on faction and Player vs. Player (PvP) status. Non-Player Characters are AI-controlled characters that can only interact with PCs through scripted events or artificial intelligence (AI).

There are three types of NPCs. Friendly NPCs, whose names are displayed in green, cannot attack friendly characters and vice versa. Hostile NPCs, whose names are in red, are either of the opposing faction or are mobs (enemies controlled by AI) and will freely attack any PC with whom they are hostile. Neutral NPCs, whose names are displayed in yellow, are neutral and will only attack if provoked.

Some NPC interaction is affected by the reputation a PC has with them. For example, certain NPC merchants will have more items available for sale if that PC has a higher reputation with the merchant’s faction. PCs’ standing with a faction can be increased or decreased by killing certain mobs or handing in items to certain NPCs. However, PCs cannot gain reputation with opposing factions, so a Horde character cannot gain reputation with any Alliance-only faction and vice versa.

NPCs in major and minor cities can buy and sell merchandise, train class and profession skills, give quests and provide a large number of services that are needed in the game. While some will merely offer advice or further the story, others, such as city guards, patrol around set paths to keep cities defended against attacking PCs or hostile NPCs that may attempt to invade.

Characters in World of Warcraft are tied to specific user accounts. User accounts can be used on all servers, or realms. Characters can be moved between servers in the same region (e.g., from one European server to another, but not from a European server to an American one) for a fee. As of this time, one may move a character from a Player Versus Player (PvP) realm to another PvP realm, or a Player Versus Environment(PvE) realm, but one may not move a character from a PvE realm to a PvP realm. The two playable factions currently in the game are the Alliance and Horde both consisting of five different races each. There are a total of 9 playable classes. The Burning Crusade expansion added one new race to each faction (the Blood Elves and the Draenei).
