Will Wright is one of the best-known names in videogames. He hopes 'Spore' will spark an interest in evolution, astronomy and the possibility of life on other planets. Will Wright, the main mind behind 'Spore,' has injected a lot of science into the game. From primordial ooze to space, 'Spore' is a guided tour of evolution that allows players to witness how their decisions might impact the entire development of a species on a physical and societal scale. 'Spore' is an attempt to 'sim,' or simulate, well, everything. That makes it time to learn what all the fuss is about. The full version of 'Spore' has already hits stores in Europe and South America, and it will land in North America this weekend. Fans have incubated over 3 million creations since the software was released in June. Its 'Creature Creator,' a software application (available as a limited demo or a $10 stand-alone product) that lets people design their own creatures, has already received a warm reception. Analysts project the software, which will retail for $49.99, could sell 2 million copies during its first month. That means fans are expecting 'Spore' to also be big, perhaps evolving into a 'Sims-'sized franchise.
