nope, StarCraft factions (most likely) come from Warhammer40k.
- the Zerg (and its hivemind) are a version of the Tyranids [1]
- the Protoss are adapted from the Aeldari [2]
- the Humans are, well, Humans. with the ghost units being adapted from Psykers [3] and Marines being adapted from the 40k Space Marines [4]
The rumour is that Blizzard wanted to make a Warhammer game, but Games Workshop - the owner of the Warhammer IP - pulled out of the deal, so Blizzard modified their game's universe a a bit and called it WarCraft and later took a similar approach with StarCraft.
