Angatar:

I love how everyone *** when something looks similar, when the Pelican was blatantly stolen from Aliens and Starship Troopers, as are the Marines, Spartans, and Infection Form. Then there's the Terran-UNSC, Protoss-Covenant, Zerg-Flood, Xel'Naga-Forerunner relation.

Starcraft was originally a Games Workshop Warhammer 40k game. So actually the Terrans are the Space Marines, the Protoss are the Eldar and the Zerg are the Tyranids.
