For some, it's the realisation that Superman isn't real. Or that their parents had lives before they were born. But for me, the revelation that rocked my childhood was the discovery that pinball wasn't just about flipping a chrome ball as high up the playfield as possible - turns out there's a structure at the heart of this hypnotic pastime.
Pinball hasn't had an easy roll since the arrival of the video game, which by the late 1990s had effectively run its mechanical cousin out of Arcade Town - according to the internet, only one manufacturer of tables soldiers bravely on these days.

"Pinball video games are quite rare, so it’s nice to see that System 3 have published Williams Pinball Classics on to the PlayStation 3."
Irish gaming site www.Bone-idle.ie writes "Williams Pinball Classics is very much aimed at the Pinball fanatic, featuring ten of the most popular real life tables that decked out the arcades over the years. From the moment you start the game it’s a trip down memory lane pumping coins into the Pinball machines and of a misplaced youth (as of course I will never make a living out of playing games)"
