Starcraft basically like aliens vs predator terrans the marines predator are protoss and aliens are Zerg :)
Nah, Starcraft is more akin to Robert A Heinlein's "Starship Troopers"
With the Bugs as Zerg, the Federation as Terrans, and Skinnies being Protoss.
Makes sense. Very, very similar actually. Skinnies are Psychics with advanced technology, Bugs are still highly adaptive evolving... well... bugs with a Hive structure and Queen, and the space faring Humans with powersuits are still space faring humans with powersuits.
