Goes for a while but is in depth. The publisher is lacking some advanced pin knowledge, I think his forte is more arcade, however he asks some good questions towards the end about the notion that Stern are behind the times in innovative features which Gomez is put on the spot but answers well. His explanation of business related matters that would effect the design of a new cabinet for instance is very interesting. Loved the room dedicated to the torture testing of machines and components. Get a nice look into Gary's office as well. Certainly the best quality vid of any Stern factory tour.
