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.
Warcraft
The first three games in the "Warcraft" series, including their expansion packs, were all released on both the PC and Macintosh. All of these games were of the real-time strategy genre. Each game proceeded to carry on the storyline of the previous games, and each introduced new features and content to improve gameplay. "" was the first game in the series to feature play over the internet using Battle.net, although this was not included until a later release of the game. "Warcraft II" was also the first in the series to be re-released as a "Battle Chest", a bundled copy of the game containing both the original and expansion. "" was the first game in the series to feature a Collector's Edition, which all subsequent games have released as well. "Warcraft III" and "World of Warcraft" also have both had "Battle Chests" released for them subsequent to their initial release. The "Battle.net" edition of "Warcraft II" was also the first to introduce the use of CD keys to the series, requiring each user online to have their own copy of the game in order to be able to connect. However, a CD key is not yet required to play via a Local Area Network, although speculation is that future games in the series will do so, as another product in Blizzard Entertainment's portfolio, "", is doing so by removing the option for using LANs altogether, requiring the use of Battle.net.
