Quoted from KingPinGames:i think that you would be really shocked to know how many "non pinheads" own Wizard of Oz or The Hobbit. especially Wizard of Oz, this game just appeals to a much, much larger audience than pinball players. I currently have two different clients that are only into pinball now because they saw a Wizard of Oz and loved the art, light show, and style of the game. I would be willing to make a strong suggestion that more Wizard of Oz pinballs are owned by people that never heard of pinside than you think.
Agreed, WOZ is a phenomenal theme which transcends pinball.
Anyone with children or a sense of nostalgia is immediately attracted to the game.
