Warcraft: Orcs and Humans : Campaign Human

Warcraft: Orcs and Humans was one of the first real-time strategy games, produced by Blizzard Entertainment and released in 1994 for DOS and in 1996 for MacOS. The game deals with the conflict between two enemy races, humans and orcs. Most units are similar and analogous, however the magic/religious units are not the same, which can be a significant factor in choosing races in a multiplayer match.
