If it's Aerosmith, I learned it just arrived in Belgium (just saw an hour ago a friend of mine is also at a distributor to pick his up) so it can only be brand new.. there won't be any possibility that the game has sat at the dealer as it was not in the country before, the container just arrived.

If it's Carl you buy from, then he probably has a few other boxed NIB games in his truck when he's delivering to you, he doesn't even has time to unpack them, he just loads and visits all his buyers to drop off the machines..

Further when you unpack you will notice that some assemblies on the playfield usually are locked with zipties and have a paper note specifying you to remove them before playing.
