Warcraft
In 2004, Blizzard Entertainment moved the series away from the real-time strategy genre and released "World of Warcraft", a massively multiplayer online role-playing game (MMORPG). Requiring a subscription fee to be paid to play, it also introduced regular additional content to the series in the form of patches. "World of Warcraft" gained popularity worldwide, becoming the world's largest subscription-based MMORPG in 2008. The game reached a peak 12 million subscribers worldwide in October 2010. "World of Warcraft" has had seven expansions as of 2018. During the production of "", Blizzard co-founder Frank Pearce stated that "If there's a team that's passionate about doing another "Warcraft" [real-time strategy], then that's definitely something we would consider. It's nothing that we're working on right now, we have development teams working on "", "", "Diablo III", and when those teams are all off the projects they're working on, they'll be intimately involved in the discussions about what's next".
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.
