CNN: 'Spore' creator ready for game's debut

Creating life forms from scratch is only a piece of the final game, which allows players to go from squirming singled-cell organism to fully fledged space-dwelling civilization. Published by Electronic Arts and developed by Wright's Emeryville, Calif.-based studio Maxis, "Spore" takes a microscopic look at players' choices and their repercussions.

Unlike Wright's people simulator "The Sims," which went on to become the best-selling PC game of all time, the ever-changing gameplay in the five levels of "Spore" fluctuates based on decisions made by the user about their species, such as choosing to become a carnivore over a herbivore or deciding to destroy other creatures instead of socialize with them.
