Manfred Dworschak reports in
Der Spiegel (18.12.2006) about the forthcoming game "Spore". It allows users to play and supervise evolutionary processes. Its creator is Will Wright who also invented "Sims". The game (according to
Wikipedia) plays evolution over five phases, from the pool phase, creating higher forms of life, communities, cities, and in the end space exploration. It's a game to design new worlds, not play combat, hence a single player game. But players may download from a central server the creations from other players. Spore has been already featured by Stephan Johnson
in the NY Times (8.10.2006).
