StarCraft enhanced on its predecessor Warcraft II, which showcased 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 while in the lesser-identified 1996 SSI release War Wind. The device styles accessible to Every single race define its racial identity. The Protoss 무에타이 can industry highly effective and high-priced warriors and machinery, whilst the Zerg depend on sheer quantities and pace to overwhelm their opponents.

The protoss OST was created to be "deep, potent, and cerebral."[28] It was extra orchestral in comparison to the terrans, and Stafford focused on instrumentation that will keep them emotion really distinct from Warcraft, having inspiration from Jerry Goldsmith's rating for the movie Alien. Cautious of parallel growth, he purposefully avoided the movie Starship Troopers.
