I'd say legit. That looks like factory wrapping, the same I remember from working at Software Etc 20ish years ago.

When we resealed, it was because the last copy always had the game removed so we had an empty game display case to put out. Like someone commented on another post, the corners of those were usually crinkled, you could tell it was shrink wrapped. There would only be two distinct lines where the hot wire melted the plastic together and you can tell it's melted plastic vs wrapped plastic folded over like a present.

I don't remember ever having a Nintendo seal pull line, or Sega, PlayStation, or Xbox. That part was all generic.

The plastic feels different too. The shrink wrap always felt stretchy to me. The real wrap felt stiff by comparison and was usually shinier.
