Are you quite new to gaming, the reason I ask is that there has been a buzz about Spore for quite some time now.
It's a new game developed by Sim City Creator Wil Wright. You develop a civilisation from a single celled organism to the space age. It's been delayed a few times now.
If you need more information, there's the great invention I've heard of where you can find all kinds of stuff. It's called the 'internet' I think.
EDIT: Hmm, I'm being something of a tit today. To make up for it, here's a link to the official Spore site - http://www.spore.com/
