one game will not save pinball

Wind the clock back, back to a time where we fell in love with these wonderful machines
yes, there was one game that drew us in, but what kept us coming back was the next game, would it be even better?

when I grew up, there was a machine at the local Fish & Chip shop.
looking back they had most of the classics there, but as a kid I did not care
what I did care about was that next month there would be a new game, new challenges

until there is a time where locations change the game on a monthly basis, then pinball will remain a niche market
