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.

When new content is added to the game, official system requirements may change. In version 1.12.0 the requirements for Windows were increased from requiring 256 MB to 512 MB of RAM. Official Windows 98 technical support was dropped, but the game continued to run there until version 2.2.3. Before Mists of Pandaria, World of Warcraft will officially drop support for Windows 2000.
