[Wikipedia] Spore is a multi-genre massive single-player online metaverse video game developed by Maxis and designed by Will Wright. It allows a player to control the development of a species from its beginnings as a unicellular organism, through development as an intelligent and social creature, to interstellar exploration as a spacefaring culture. It has drawn wide attention for its massive scope, and its use of open-ended gameplay and procedural generation.
