I can maybe understand putting the game in showrooms or at pinball shows in that state, but putting it on location that unfinished is just wrong... The whole thing could backfire-yeah, people will think "ooh, shiny", try the game out, and not be able to "do" anything in it. This either gives people a new bias against pinball, or reinforces that pinball is "boring" to them, and means they won't take a second look. Like it or not, Gary Stern had a point when he said that just about anyone needs to be able to interact with the cool features on your game (famous example was the "bash balrog" on LOTR I think). Not to say that a game can't be challenging, but you also need to let people think they're accomplishing something meaningful. Look at how many people remember something like "Mamushka" on TAF-all it did was change the music and start a frenzy mode, but it was easy to start, and made you feel like you did something successful in the game (other than just increasing your score).
