Dune II and the Prototype
Dune II: The Building of a Dynasty (1992), developed by Westwood Studios and published by Virgin Games, established the mechanics that Warcraft would refine: resource collection (spice harvesting in the desert setting), base construction with different building types serving different functions, unit production from buildings, and real-time combat in which groups of units moved simultaneously across a visible map. The game drew from the Herbert novel's political structure — three houses competing for control of the desert planet Arrakis — to provide three factions with different unit types. The mouse-driven interface, using point-and-click to select units and issue orders, made the game approachable for players who had never played strategy games.
Dune II was not a multiplayer game; it was a single-player campaign in which the player fought increasingly difficult computer-controlled opponents. This was the primary limitation that Warcraft addressed. Blizzard's Allen Adham and Patrick Wyatt, developing Warcraft: Orcs & Humans in 1993-1994, identified multiplayer competition as the mode that would make RTS games genuinely compelling: real-time strategy against a human opponent who adapted to the player's strategies was a fundamentally different experience from playing against AI that could be pattern-recognised and defeated predictably.
Warcraft's Design Choices
Warcraft: Orcs & Humans simplified Dune II's resource system to a single gatherable resource (gold) supplemented by a secondary resource (lumber) that was introduced in Warcraft II. The simplification made the economic game faster to learn without eliminating strategic depth; two resources created a trade-off between military and economic investment that single-resource games could not produce. Unit types were more differentiated than Dune II's factions — footmen, archers, catapults, and magic users each had distinct combat roles — and the game's two factions (humans and orcs) were genuinely asymmetric rather than statistically equivalent recolours.
The production quality that Blizzard brought to Warcraft was notably higher than Westwood's Dune II: voice acting for units, animated character portraits during dialogue sequences, and a coherent fantasy world with established lore and geography. When a player clicked a unit repeatedly, that unit would respond with humorous quotes — a design decision that humanised the otherwise abstract game pieces and created memorable moments that players quoted to each other. "What do you want?" and "Stop poking me" became embedded in the gaming culture of 1994-1995 in a way that suggested Blizzard understood entertainment as well as game mechanics.
Warcraft II and the Genre's Peak
Warcraft II: Tides of Darkness (1995) was the game that made RTS the dominant PC gaming genre. The sequel added naval units, air units, and a third dimension of combat that required players to manage land, sea, and air simultaneously — a complexity that rewarded experienced players without overwhelming newcomers who could focus on land combat while learning the game. The graphics were significantly improved; the sound design was more polished; and the multiplayer, now supporting up to eight players via modem or IPX network, was the central focus of the game's appeal. Warcraft II sold over two million copies and became the best-selling PC game of 1995.
The game's multiplayer community was self-sustaining in a way that had not previously existed for a game without dedicated server infrastructure. Players organised games through bulletin board systems and early internet communities, developed strategies, created maps using the built-in editor, and competed in informal leagues. This community infrastructure — player-organised, publisher-independent — prefigured the competitive scenes that StarCraft and later Counter-Strike would develop into professional sports. The players who spent hundreds of hours on Warcraft II multiplayer in 1995-1996 were the generation that would create esports.
The Path to StarCraft
Command & Conquer (1995), also from Westwood, competed directly with Warcraft II for the same audience and generated its own franchise that ran in parallel through the late 1990s. The competition between Blizzard and Westwood drove technical and design innovation in both series: each game required a response from the competition, creating a dynamic that produced the creative peak of the genre in the period 1994-1998. Age of Empires (1997) and Total Annihilation (1997) expanded the genre's scope; StarCraft (1998) refined it to a competitive precision that transformed the genre into a professional sport in South Korea.
StarCraft's three asymmetric factions — Terran, Zerg, Protoss — were designed with competitive balance as the primary objective, creating a game where human players at high skill levels competed on more equal terms than any previous RTS had achieved. The game sold ten million copies worldwide, including three million in South Korea alone, where it generated professional leagues, television broadcast deals, and a dedicated audience that treated it as a serious sport. The pathway from Dune II's desert spice-harvesting to StarCraft's televised professional leagues took six years and passed through Warcraft — the game that first demonstrated the commercial and social potential of real-time strategy at scale.
