Developed by Maxis, Spore has players managing the evolution of their creatures from the cellular level all the way to the point of interstellar travel. The universe--populated by other player's creations in a unique single-player MMO system--will introduce multiple gameplay elements, including simulation, real-time strategy, and action.

Spore is set for a September 7 release on PC and Mac, with a Nintendo DS version hitting on the same day. The Creature Creator application, a free download, will be out on June 17.
