Rules? We don't need no stinking rules!!
Rules fit better then requirements. Honestly, I was hoping to go with items that were in print and kind of new that don't get talked about. Things that were not horribly expensive would be nice so people can get them to talk about them. But those are more like guidelines that I didn't always follow.
D&D items do get more responses then the non D&D ones. When we got a publisher to actually talk about the book (Piazo with Classic Monster Revisted) we had the best discussion yet. Box sets are fine, City of Brass is cool and would make a good one.
