Quoted from whthrs166:

It really depends on the humidity, how the game was handled, and how it was stored. All ?s that baby has been sittin for a long time. Its really common sense: When you open a NIB game it is moved inside a dwelling or business where the temperature is controlled and there is a roof overhead. A game in a box is kept in many different places moist concrete basements, storage facilities ect... The bulbs and holder rust and filaments go bad.
