List of Blizzard Entertainment games
Since the release of "Warcraft", "Diablo", and "StarCraft" (1998), Blizzard has focused almost exclusively on the "Warcraft", "Diablo", and "StarCraft" series. The sole exception has been the company's latest title, "Overwatch" (2016). All of Blizzard's games released since 2004 still receive expansions and updates, especially the long-running massively multiplayer online role-playing game "World of Warcraft" (2004). With over 100 million lifetime accounts as of 2014 and US$9 billion in revenue as of 2017, "World of Warcraft" is one of the best-selling computer games and highest-grossing video games of all time. Blizzard Entertainment has developed 19 games since 1991 as of 2018, in addition to developing 8 ports between 1992 and 1993; 11 of those games are in the "Warcraft", "Diablo", and "StarCraft" series.
Role-playing video game
Among the best-selling PC RPGs overall is the massively multiplayer online game "World of Warcraft" with 11.5 million subscribers as of May 2010. Among single player PC RPGs, "Diablo II" has sold the largest amount, with the most recently cited number being over 4 million copies as of 2001. However, copies of the "Diablo: Battle Chest" continued to be sold in retail stores, with the compilation appearing on the NPD Group's top 10 PC games sales, list as recently as 2010. Further, "Diablo: Battle Chest" was the 19th best selling PC game of 2008—a full seven years after the game's initial release; and 11 million users still played "Diablo II" and "StarCraft" over Battle.net in 2010. As a franchise, the "Diablo" series has sold over 20 million copies, not including "Diablo III" which was released for Windows and OS X in 2012.
