There is no such thing as NOB, the running joke definition translates now as NOoB, and is completely fitting.

Once a game has been "adjusted", it means opened and played, declaring the item as used. The term used by operators is a "burn in" period at the shop. Stern (and other manufscturers) apply the same simple understanding for warranties, unless directed offered as an exception. This is described as a "floor model" or "demo", which is the same exact thing as NOB aka used.

Either a game is new or it is not, don't fall for home market or dishonest distributor tactics. It has the same worth as "under 200 plays".
