I had this huge list prepared of things I like and dislike in pinball. Then I realized most of the designers know how to make a fun game.The problem is upper management interfering with their designs. That goes back even to the 50s. More recently there are plenty of stories where a certain owner of a company, who never designed a game in his entire life, used to tell designers what he wanted in the game and what to do. It may have reduced the bill of material, but most likely not improved the game.

That's not how you make profit.
