I am going to get an xbox 360 arcade included with some furniture from roomstogo and I’m wondering what the difference between that and an xbox 360 premium is. I heard that the only thing was the hard drive. If that is the case then could I just buy a hard drive and it would be the same thing as a premium? And also if I did that, could I use xbox LIVE?

I found a skull in HALO 3 that apparently doesn’t regitar with the game at all. It’s in the last level, after rescuing Cortana. When you have to go back and destroy the reactor. In the big open room where you do this, it’s possible with someone’s help to get up on the upper level that runs around the whole room. Up there you will find a skull. But, it doesn’t show up on the skull activation screen. And, you got no achievements for it. What gives?
