StarCraft improved upon its predecessor Warcraft II, which featured two extremely similar playable factions, by introducing asymmetry between the models and systems accessible to its 3 races (Protoss, Terran, and Zerg). This asymmetry was similar to that pioneered in the lesser-known 1996 SSI launch War Wind. The device varieties available to each race determine its racial identification. The Protoss can discipline potent and costly warriors and equipment, when the Zerg rely on sheer numbers and velocity to overwhelm their opponents.

We realized that our Terrans have been going to be tough and soiled. We knew we wanted the Protoss to generally benot savage, just, but primal, and effective. And we knew we 다이어트 required the Zerg to swarm."
