Well, it is minty-fresh, but geez, it's maybe R4. I guess it's possible that a game could / should have a different rarity factor loose or in the box. For instance, the rarity of a Genesis game in a clamshell compared to a loose cartidge would be nearly the same, because the case was durable and nice to display. A cardboard box for a 2600 or NES game would get beat up and be discarded, making the box rarer. I don't know, but to be honest, I have seen loads of Deadly Duck carts and I had never seen this box before. Morgan
I see one on my shelf every day. I don't think I have ever seen that manual before though. Mine is the standard blue.
