Medieval Madness is a Williams pinball machine released in June 1997. Designed by Brian Eddy and programmed by Lyman Sheats, it had a production run of 4,016 units. It was an immediate critical success, earning well on location and achieving widespread popularity among collectors. Demand for the machine soon outstripped supply significantly; as of 2005, Medieval Madness machines often sell for prices well in excess of $8,000, sometimes much higher if in pristine condition (when purchased new in 1997, the machine cost approximately $3,000).
Much of the game’s dialogue was written by Scott Adsit and Kevin Dorff, at the time members of the The Second City in Chicago. Adsit also provided voice work alongside fellow Second City member Tina Fey. On October 18, 2013, Planetary Pinball Supply announced that they would be taking $1,000 pre-order deposits for a reproduction run of Medieval Madness. On March 12, 2015, Planetary Pinball Supply confirmed that MMR shipments had begun to end users
