Okay this is not kinda RTS game but there's none other category here that suits this game the most. Basically this is a sim game. What I meant 'sim' is where you'll build something up from scratch. Designing the outlook to its inner characteristic. But its no TheSims or SimsCity. Its spore. From the same studio, Maxis. This game revolutionized the simulation genre by allowing player to create life! From micro uni-cell to walking on the land then adding eyes, hands, claws, paws, tooth or whatever else. You are actually acting as a god designing a creature!
Here's a brief preview...
It divides into 5 stages. From initial cell stages where you decide you creature as either a carnivore , herbivore or even an omnivore.
Then you proceed to creature stage.This where u design how ur creature looks like. Whether it walks on 2 legs or 4 legs. Whether does it hunts or socialize.
Proceeding to tribal stage, your creature developed brain power and learn to unite as one. Dominating other creature with your tribe's uniform.
Civilization age is the similar age to current humanity technology. Where we developed aircraft, ships and land vehicle to ease us.
Space ages allows players to send their creation to outer space. Expanding their empire in the endless and borderless space.
