Sly Cooper & the Thevius Racoonuus. It's such an awesome game. As I have just got done playing the demo, and am still giddy. I got so into it, so I think everyone else needs to go track down a demo of it and play away. It is one of those really good adventure games that everyone can get into. And Sony has been very gracious in giving about an hours worth of play time in the demo I played today.
Oh, the little raccoon is so cute with his silent skills and cute little fluffy tail that floats behind him! Everyone should get this game when it comes out.
