The Ravensburger Edition
According to the Archives Manager at Ravensburger, Scotland Yard began production in 1979 at the Otto Maier Publishing Company (now Ravensburger). There were six people involved in the development--Werner Schlegal the editorial manager, a product manager, a purchasing manager, a graphic designer, and a game editor. The team was asked to develop a world travel game in June of 1979. After a few months in development, the team had decided on a foxhunt. The "fox" eventually turned into the infamous Mr. X, and the hunters evolved into detectives. Finally the team chose the famous London police station, Scotland Yard, and adopted a map of London for the board.
Scotland Yard even inspired a sequel, "Mr. X," which pits the detectives in another romp throughout the highways and bi-ways of their fair land in an attempt to capture the famous bad guy.
You can buy the older Ravensburger edition of the Scotland Yard board game at Amazon, eBay, or Board Game Geek for about $20.00, while the updated edition is available online at the Ravensburger website for $39.99.
Perhaps the coolest feature of the Ravensburger games is the nifty Mr. X visor, or in the newer versions, the baseball cap. They are exclusive to the Ravensburger game, so you will have to shell out the extra cash if you are looking for an addition to your wardrobe and not just your game closet.
