I don't blame the OP for not opening it, so why all the fuss?
It's DE Playboy, not Addams Family, what does he really have to gain by opening it up? He's doing the smart thing by keeping it a mystery/closed, as it's been for 28 years.
If the OP really wanted a DE Playboy, he'd throw a grand or so at a used one, which is what this basically becomes once you pull the staples out.
Chances are the game is fine, very cool to see a nib DE anything, it's too bad it's not a better game.
