I think that this is a cool idea.
I have always wondered if you took one machine, perhaps one that is not too deep.
Show a segment with that machine trying to demonstrate the rules; that pinball is not just about hitting the ball with the flippers (to keep it alive), but to complete something to get somewhere and obtain points, light show, etc.
I think one of the barriers to new people getting interested in pinball, is that they don't understand what it's about.
So if you showed how a machine is developed, designed, themed, mechanics built, software integrated, rules made; then what I have said above is the culmination of all of that effort...and why that machine was built and why it is unique, fun and worth seeking out to play.
