Spore is a computer and video game under development by Maxis, and designed by Will Wright. It simulates the complete history and future of life according the evolution theory. Its concept, scope, and development philosophy (broad use of procedural generation) has drawn wide attention.

Spore is, at first glance, a "teleological evolution" game or god game: the player molds and guides a species across many generations, growing it from a single-celled organism into a more complex animal, until the species becomes intelligent. At this point the player begins molding and guiding this species' society, progressing towards a spacefaring civilization. Spore's main innovation is the use of procedural generation for many of the components of the game, providing vast scope and open-endedness. Wright said "I didn't want to make players feel like Luke Skywalker or Frodo Baggins. I wanted them to be like George Lucas or J.R.R. Tolkien."
