Who knows what will be the ‘in thing’ in 10-20 years time

Most of us here are in the 35-50 yo age group, we grew up with pinballs around us, in fish and chip shops, milk bars and arcades. Speaking for myself, I am trying to recreate the world from when I was about 12-15 yo (but a better version of it)
Also at our age, we tend to have a better disposable income, our job has improved, maybe the kids have moved out, the house is paid off. We can now afford those things we always dreamt about

So the question is, what will be important to those who are currently 25yo?
They did not grow up with pinball, arcades had either dancing machines or redemption games. But these are the children of the Playstation and Nintendo. They will be probably paying big $$$ for the original Playstation  and
original games. Games like Tomb Raider will be making huge comebacks

Pinball will be forgotten once more

I'm with Pete, so many pinball machines have been brought into Australia that we probably have more pins per member of population than any other country. Majority of kids don't care for them, so when us oldies start downsizing and off loading, I predict most will plummet in price. Big falls.
