Something I think is worth asking but has not been asked yet:
Why do you want pinball to become big? Are you willing to accept changes to what pinball is if it means it will grow the medium?
I would prefer it if pinball became big too, but I've met people who are fans of niche things and openly resent when it becomes more popular or get angry at the thought that it could become more popular. The most common reason behind that is that they like whatever it is just the way it is and know that its appeal is limited, and that they figure the only way it could become more popular is if it changed to appeal to a wider audience. That is, they will not compromise and are afraid what they like will fall into "Lowest Common Denominator." This mindset is pretty common in circles related to music, anime, and certain types of video games.
Then there are the hipsters, the people who get into things because they're niche and/or impenetrable. To them, they enjoy being part of small communities and/or feeling superior to the people who aren't into it, as it makes them feel special. When something becomes more popular, these people will abandon ship and move to something that's still unpopular. I see this come up often among hardcore fans of beer, board games, and food: I see an adage all three of them have in which things that are advertised cannot be good because good things must stay small and become known through word of mouth.
I tell some of these people about how pinball fans, by and large, want pinball to be more played and more popular, and it absolutely confounds them. In at least one cases, the person I was talking to got offended at that statement.
Seriously? They do? What do they call bumpers then?
It makes me think ofthe people who call laptop computers as "notebooks": What do they call the notebooks made of paper?
Whoever that is already ahead of the curve--he's paying attention to the DMD.
