StarCraft is a science-fiction based real-time strategy series first released on March 31, 1998, another product of Blizzard Entertainment.

General

 * The Archon is an energy-based being, similar to protoss archons.


 * Hydralisk and Ultralisk skulls can be found in the background of Diablo III.

StarCraft

 * In reference to the Secret Cow Level, the phrase "there is no cow level" is used as a cheat code.


 * The protoss Observer, if clicked on enough times, will state "I sense a soul in search of answers." This is a line taken from the Diablo character Adria. The Arbiter will react similarly, albeit "We sense..."


 * Another quote from the Observer is "That sounds like a... a huge, gargantuan, swollen, bloated mushroom!" This is taken from Griswold's comments during the Black Mushroom quest.


 * The setting of the Diablo series is a world named Sanctuary. A region of Shakuras in StarCraft is named likewise.


 * A battle.net multiplayer map for StarCraft is named Diablo and patterned after the Satanic pentagram motif used in Diablo games.

StarCraft II

 * A Diablo unit exists in the game and can be placed in player made maps with the game's map editor. Diablo also has a cameo in one of the campaign missions, where he appears to control the rising and lowering of a deadly sea of lava.


 * There is also an horizontal billboard advertising some of the latest Cineplex 5000 movies, one of them being Diablo: The Musical, in another one of the campaign missions.


 * There is an achievement titled Stay Awhile and Listen after listening to all main characters throughout the single player. This phrase is a reference from Deckard Cain in Diablo II.


 * Some portraits and decals are Diablo-themed


 * A probe pet and protoss-themed transmog set will be available through the collector's edition of Legacy of the Void.
