Spore coming in Sept., complete with music by Brian Eno

In 2005, Will Wright's Spore stole the show at E3. Then the next year this happened again, as the game's "SimEverything" approach seemed nearly ready for release and looked increasingly polished. Well, it's been more than a year since then and finally the game has a release date: Sept. 7. At the very least, this should take the game off the Vaporeware awards list, and quite possibly push gaming itself a good deal forward.

"We're in our final stages of testing and polish with Spore, and the team at Maxis can't wait to see the cosmos of content created by the community later this year," said the game's designer Will Wright. Wright was one of the founders of Maxis, and went on to create the SimCity series of games and eventually its mind-blowingly popular successor The Sims.

Spore began production back in 2000, so what took so long? The game is based upon a revolutionary concept of procedural gameplay, where a player's choices in one stage of the game affect later portions. While this doesn't sound too incredible, the film's scope makes this a big thing. Players begin the game by guiding low-level cells, then moving on to land, creating societies and eventually leading their creatures out to space.

Procedural generation is also inserted into other portions of the game. In specific, the game's music is being designed by Brian Eno to change based upon the player's choices. Eno began working on the game over a year ago and the way music is generated may in some ways be as interesting as the game itself.

Spore will be out, in one form or another, for PC, Mac, Nintendo DS and Mobile phones. Check out the game's teaser trailer below:
