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 during the lesser-recognised 1996 SSI launch War Wind. The unit varieties available to each race determine its racial id. The Protoss can discipline highly effective and high-priced warriors and machinery, while the Zerg depend on sheer figures and pace to overwhelm their opponents.

At the same time, Blizzard has introduced that new commanders are prepared to become extra to the Co-Op method in Legacy with 다이어트 the Void as a DLC,[53] with Karax being the first addition provided without cost.
