Gary Stern is as we speak the KING of pinball. He runs shit when it comes to pinball. There's no idea you or I can come up with that he hasn't heard 10,000 times, and he has a reason not to do every damn one of them.
The reason he won't do a non-licensed pin is because operators won't buy a non-licensed pin, and the home buyers who buy pins as status symbols won't buy one.
The only people that would buy non licensed pins are collectors and pinheads, which isn't the majority of his market. Gary claims that a large portion of the home sales are to people who only buy 1, and only play it for a few weeks and then leave it turned off sitting in the Den, and they brag about it when company comes over. They'll buy a Batman pin, but they won't buy a non-licensed pin.
If they don't buy a license for a pin, then now they get to draw every inch of the artwork on every inch of the machine. That's character development money, extra artists, etc. Right now they just do it all digitally with existing artwork.
If they do an LCD with no license, then they have to hire animators to create characters and artwork for the LCD display.
OR, they can pay what Gary says is about $50 per machine for a full theme and artwork package of something people are familiar with, and already know how to play before they step up to the machine. When you play a Batman machine, you know that you want to drive the batmobile and you want to beat up the Joker. When you play "Old City Blues" or whatever a non-licensed pin would be, how do you play it? It just doesn't make the same money from casual players out on location that a licensed pin would.
I mean what it comes down to is: it ain't gonna happen. What you're getting is what you're GOING to be getting for quite a while, lol.
Now... don't construe this as my support for it. I'm just saying, from a business perspective, I see why he does what he does. I'm not sure there's a better way to do it. There may be a way that you or I would enjoy more....... but that doesn't mean it would keep them in business, and it very well might push them out of business.
I mean, it's like asking Willie Nelson to quit writing all that bullshit music he's done now, write one more "On The Road Again", and then kill himself. lol. I think I'd prefer him to keep putting out mediocre albums.
Similarly, do you want Stern to blow their load on 1 last great game, then close like Williams did? Or would you rather them putt along, doing mediocre games. I think the two are PROBABLY, mutually-exclusive right now.
