Warcraft: Orcs & Humans is a real-time strategy game (RTS), developed by Blizzard Entertainment and published by Blizzard and Interplay Entertainment. The MS-DOS version was released in 23 November 1994 and the Macintosh version in late 1996. Sales were fairly high, reviewers were mostly impressed, and the game won three awards and was a finalist for three others. There was a CD re-release, namely version 1.21 (CD version), that didn’t have the word-from-the-user-manual copy protection of prior versions. The sequel, Warcraft II: Tides of Darkness, became the main rival to Westwood Studios’ Command & Conquer series, and this competition fostered an RTS boom in the mid to late 1990s.One player represents the Human inhabitants of Azeroth, and the other controls the invading Orcs. Each side tries to destroy the other by collecting resources and creating an army. In addition both sides have to ward off dangers from wild monsters, but sometimes can use some monsters as troops.
