Seems there is confusion around these terms, especially the newest term NOB which has been used buy new Pinball dealers for quite sometime. NIB, NOB, DEMO all have an expectation for condition. While USED and HUO do not. Feedback appreciated.
NIB (New in Box) - Still in the box with zero plays, will need subtle adjustments and tweaking to dial in the game to play perfectly. Condition: as new, no wear, etc. New factory warranty applies, Buyer is the first owner.
NOB (New out of box) - seems simple as well, this game was opened by a dealer and inspected, adjusted and tweaked (i.e. Dialed in) being sure the game is problem free and ready for the new owner to enjoy. Game has a few plays but HAS NEVER been owned by anyone else. Condition: as new, no wear, etc. New factory warranty applies and buyer is the first owner.
DEMO - This is a game with 50 plays or more (IMO) which was displayed by a dealer in a commercial space such as a show or event. You can add your list of uses here. The point is that it was played enough to show some use. Many of my customers prefer these because all of the bugs are worked out and the discount is substantial per play, yet they are still the first owner of a new game. Condition: may have very slight wear from use. New factory warranty applies and buyer is the first owner.
USED - Buyer purchased from a dealer, opened and played it. Has had one or more owner, warranty not applicable. Condition: No expectation, must be described
HUO (Home Use Only) - This is a used game USED in a home environment ONLY. Nothing more, usually unproven and almost irrelevant. Condition: No expectation, must be described.
I think having a clear expectation of all sellers avoids buyer confusion.
