StarCraft improved upon its predecessor Warcraft II, which featured two very similar 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 during the lesser-regarded 1996 SSI launch War Wind. The unit kinds available to Each individual race determine its racial identification. The Protoss can area potent and expensive warriors and equipment, even though the Zerg count on sheer numbers and velocity to overwhelm their opponents.

The protoss OST was built to be "deep, strong, and cerebral."[28] It had been much more orchestral than the terrans, and Stafford centered 격투기 on instrumentation that might maintain them feeling particularly unique from Warcraft, taking inspiration from Jerry Goldsmith's rating on the movie Alien. Cautious of parallel growth, he purposefully avoided the movie Starship Troopers.
