Please see photos for more details. Launch edition and still factory sealed as far as I can tell. I did some research and found that while the shrink wrap doesn't have vent holes that doesn't mean it's inauthentic. Also, it is sealed around 3 out of 4 sides so that is a sign that it is still factory sealed.
As far as the game itself: Easily one of the greatest games of all time which definitely makes this a rare item in its unopened state. C Soundtrack, Gameplay, Graphics, Artwork.
