Amazon.com and Gamestop.com now have listings for Spore: Galactic Adventures, a Windows and MacOS product with a $29.99 price tag and a March, 2009 release date. There are no other details, but from the available information it seems likely this is the second expansion planned for Spore, EA's life simulation, as there have already been indications that a coming add-on would concentrate more on space exploration.
