Actually, I do have one question. I can't see my old 360 purchases in my game library or on the Xbox website, but if I search for them manually on the store it shows that I own them and can redownload. Thing is, it's a tad difficult for me to remember every digital game I bought from 2008-2011. Is there a way to tell or list these other than dragging my 360 out of the attic and hooking it up?
Hmm... I think your (current) best bet is filtering through your achievement list or moving all your saved 360 purchases onto an external USB harddrive (if you have one).
