Everything is in the Marketplace right now. A few cool demos, a few neat trailers... and a huge portion of Halo 3. I'm downloading it right now, so I have no idea what it's like, BUT, it's 104 MB. So it's pretty substantial.
If you have a 360, get to the marketplace right now.
the halo 3 demo looks awesome and its going to look like a good game, but another game that looks amazing right now is Fable2, i downloaded that trailer and it looks awesome. I cant wait for both of them
It wasn't a demo, it was a trailer. Anyways I got most of the stuff off Marketplace along time ago. Favorite thing would be the Moto GP demo or the Lost Planet demo. Both kicked ***.
Oh, Fable 2 was CG footage, Psy.
