Quoted from drfrightner:This happens to every generation, people who're 40 to 60 raise values of those cars, those toys, and those games.
For the younger gen we're living in a World that what was old is new again. Places like Punch Bowl Social have vintage arcades, and so do a lot of other places.
Its vogue!
When people reach 40 to 60 they have money to spend and usually its something they remember fondly, like getting back your first car, or a car you always wanted, or getting back toys you had as a kid.
Its really that simple.
Pinball real heyday was in the 90's someone who was 20 in 1990 is now 48 years old.
Nailed it!
