yeah this
Nintendo didn't have any kind of distinct shrinkwrap that guaranteed your game was factory sealed until the Gamecube and DS. Stores like Target would often re-shrinkwrap games people returned and then sell them as new, because video games weren't treated like sacred artifacts, just like every other product that's not consumable, and nobody cares. They did have a policy where you couldn't return video games, but plenty of angry moms would pressure the employees and they usually gave in, and it was practically an unwritten rule that you could get away with it no problem on the day after Christmas. That's why it's silly to hold sealed copies of cardboard box-era Nintendo games in high regard.
