Needless to say, the game requires more RAM on Vista because the OS itself is more hardware-hungry. Up till now, the only eyebrow-raising requirement is the 6GB space. But do expect an update to these specs.
Spore will be release on September 7 on both PC and Mac. The Nintendo DS will also get its own simplified version of the game, dubbed Spore Creatures.
