While not a gamer myself, it's been hard to avoid the buzz surrounding Spore, the new game created by "god game" pioneer Will Wright, due in late 2007. The game traces the evolution of an organism from the cellular phase to interplanetary exploration, with infinite different possibilities as a creature emerges from the primordial ooze. Cool.
With such a heady concept, who better to provide the score than legendary philosopher/soundscaper Brian Eno, who has announced that he is indeed providing the music to the game. But of course, it's not that simple. WWMNA reports from a recent Eno lecture in Berlin:

"Generativity plays a role in many fields now, with gaming being no exception. Also built around this notion and probably one of the currently most eagerly awaited games is Will Wright's Spore, for which Brian Eno, as he revealed, will be making the soundtrack!"
Rumours of Eno's involvement have been circulating since November, when Spore creator Will Wright joined him on stage to deliver a talk on the joys and techniques of generative creation. This meeting of minds made Brian a perfect choice.
"He was asked to do it, because the designers wanted sound that is just as procedural as the game itself. He went on to demonstrate a simple software called 'The Shuffler,' which even with a simple combination of samples possibly would never create the same composition twice within a lifetime."
