For awhile there, no one was making pinball machines. Thankfully, Stern has once again started cranking ‘em out. For their (relatively) recent ‘Monopoly’ machine (as seen at the Lager House in Detroit), they contracted Pat Lawlor, famous among really cool dudes for his design of the Addams Family Pinball Machine (Highest-selling pinball machine ever). He’s posted an amazing step by step walkthrough of the planning, design, prototyping, testing, and production process for the Monopoly Pinball Machine. Highly recommended reading.
