before I out down 9.99 on a game like spore I would like an opinion on what sort of game this is. Is there a sandbox mode where I can just explore? 30 levels I hear but does it change that much if you create a different creature on a different game? How diverse are these creatures? I can always spend $10 on xbox live on a fame I already demoed so I need to ask how pol find spore after a few days of playthrough. Thanks!
