At the Game Developer’s Conference, Will Wright gives a 35-minute demo of Spore. In the game, you evolve a little creature over the eons, from bacteria to Battlestar Galactica — that, we knew. But check this out: The rest of the world (and ultimately the universe) is filled out entirely by other creatures created by other players at other times. The game plucks them from the shared Spore-verse to build a balanced ecosystem.
If you watch the video to the end you’ll get to hear Will Wright say the phrase “fractally surf.”
