Will Wright, the inventor of SimCity and the Sims, is working with Maxis to develop Spore, a game that takes the "Sim" concept to a monumental scale. The game begins with you controlling the first single-celled organism and you manipulate species, evolving creatures until you finally have created a race of intelligent, space-traveling beings. The game is split up into different "stages" representing the different states of evolution that borrow gameplay ideas from different genres. The cell-stage is played similar to Pac-Man, while the more evolved "Civilization" stage takes many ideas from the SimCity games. What separates Spore from previous Sim games is the amount of customization you have over all the flora and fauna in the world, and the interconnected nature of people's games. While you don't play against people directly the game seemlessly populates your game world with people's creations that are uploaded online. You can pick and choose which sets of creatures you want in your game world using the Sporepedia website, or setting a "friends-list".
