Although Blizzard's very successful Starcraft, first released in 1998, was set in a different universe, it was very similar to Warcraft II in gameplay and in attention to personality and storyline.

Warcraft: Orcs & Humans laid the ground for Blizzard's style of RTS, which emphasized personality and storyline. The game was the first typical RTS to be presented in a medieval setting and, by bringing multiplayer facilities to a wider audience, made this mode essential for future RTS titles. Warcraft II's predecessor Warcraft: Orcs & Humans, released in 1994, gained good reviews, collected three awards and was a finalist for three others, and achieved solid commercial success.

The fog of war completely hides all territory which the gamer's has not explored, and shows only terrain but hides opponents' units and buildings if none of the gamer's units are present. The majority of the main screen shows the part of the territory on which the gamer is currently operating, and the minimap can select another location to appear in the larger display. The more advanced combat units are produced at the same buildings as the basic units but also need the assistance of other buildings, or must be produced at buildings that have prerequisite buildings. Players must collect resources, and produce buildings and units in order to defeat an opponent in combat on the ground, in the air and in some maps at sea. The Edition, released in 1999, provided Blizzard's online gaming service,, and replaced the MS-DOS version with a Windows one. Later in 1996 Blizzard released an expansion pack Warcraft II: Beyond the Dark Portal for MS-DOS and Mac OS, and a compilation Warcraft II: The Dark Saga for the Sony Playstation and Sega Saturn. The rivalry between Blizzard's series and Westwood Studios's Command & Conquer series fueled the RTS boom of the late 1990s. The main game, Warcraft II: Tides of Darkness, earned enthusiastic reviews, won most of the major PC gaming awards in 1996, and sold millions of copies.
