StarCraft enhanced on its predecessor Warcraft II, which highlighted two quite related playable factions, by introducing asymmetry among the units and technologies accessible to its a few races (Protoss, Terran, and Zerg). This asymmetry was just like that pioneered inside the lesser-recognized 1996 SSI release War Wind. The device forms accessible to Each and every race define its racial id. The Protoss can subject strong and high-priced warriors and machinery, while the Zerg depend on sheer figures and pace to overwhelm their opponents.

The protoss OST was designed to be "deep, impressive, and cerebral."[28] It absolutely was a lot more orchestral compared to terrans, and Stafford focused on instrumentation that may hold them sensation extremely distinctive from Warcraft, getting inspiration from Jerry 헬스 Goldsmith's score into the Film Alien. Wary of parallel development, he purposefully prevented the film Starship Troopers.
