Unless you've been living in a cave for the last few months/years, you've probably heard about Will Wright's latest creation, Spore ($50 Mac/PC). In the game, you develop a species from the slog of microscopic organisms all the way up to interstellar traveling, social, and intelligent being, while in complete control of the species' development. The game's music is procedurally generated and was designed by Brian Eno, and with such a vast scope and countless gameplay options, it's no wonder the game was originally called Sim Everything.
