This game appeals to me a great deal. You get to make creatures based on the Evolution theory!
Charles Darwin created the theory of evolution. The strong will survive and the weak will perish. Even though I am not a believer of evolution, at least not anymore, I am still intrigued by the theory. Spore is a PC / wii game by Maxis and EA, the same companies that made Sim City and the Sims. You play as sort of like God, creating creatures based on the evolution theory.
But in Spore, the creatures you create would not be petite or cute like Pokemon. They are fuglier and more unique, but that is what makes the game stand out. You create creatures that are unlike real-life animals, but rather, strange-looking colorful ones... Cool!
