StarCraft improved upon its predecessor Warcraft II, which featured two very identical playable factions, by introducing asymmetry concerning 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 id. The Protoss can discipline effective and costly warriors and machinery, though the Zerg rely on sheer figures and 무에타이 speed to overwhelm their opponents.

The protoss OST was intended to be "deep, effective, and cerebral."[28] It was more orchestral when compared to the terrans, and Stafford centered on instrumentation that might maintain them feeling exceptionally unique from Warcraft, using inspiration from Jerry Goldsmith's score to your Film Alien. Wary of parallel enhancement, he purposefully averted the film Starship Troopers.
