StarCraft improved upon its predecessor Warcraft II, which featured two very similar playable factions, by introducing asymmetry between the models and systems available to its three races (Protoss, Terran, and Zerg). This asymmetry was similar to that pioneered in the lesser-recognised 1996 SSI launch War Wind. The device varieties available to each race determine its racial identification. The Protoss can discipline effective and costly warriors and equipment, when the Zerg rely on sheer numbers and 격투기 velocity to overwhelm their opponents.
The protoss OST was designed to be "deep, highly effective, and cerebral."[28] It had been a lot more orchestral compared to the terrans, and Stafford focused on instrumentation that could hold them sensation extremely distinctive from Warcraft, using inspiration from Jerry Goldsmith's score into the Film Alien. Wary of parallel development, he purposefully prevented the film Starship Troopers.
