StarCraft improved on its predecessor Warcraft II, which showcased two incredibly equivalent 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-acknowledged 1996 SSI release War Wind. The unit styles accessible to Every single race outline its racial identity. The Protoss can field impressive and high priced warriors and equipment, whilst the Zerg count 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 centered 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 advancement, he purposefully avoided the movie 격투기 Starship Troopers.
