An item need not tick off any or all of those boxes to be a Superstar Item but to sway me they certainly help. IMO there is no secret Superstar Rosetta stone but typically we all know it when we see it.
I cut the quote for brevity, but I wanted to mirror Andrew's statements. These were well thought out criteria that I could stand behind.
One of them that stands out the most to me is the "break the rules in a small but significant way". Wondrous items are your opportunity to do just that. In fact, Superstar items should per a comment from either one of the posts from the judges or a comment made from the panel discussion recorded and available on the messageboard. It's very easy to get stuck in a SAK or SIAC if you do not break the rules just a little.
As for pricing, Alexandar Augunas, this was also addressed by the judges. You didn't have to get it right, just don't get it wrong. Meaning, as long as the item was priced within the ballpark of similarly powerful items, you were going to be okay. This mechanic and the art that goes behind it, could be taught. It's the creativity that seemed to be more of a concern.
