I'm only posing a hypothetical where it is one or the other. I totally agree with Gavin, put it where you see it with ease and maybe interactive. Lots of real estate on pinballs.
To be a smart ass about the next generation, design a pinball where you plunge the ball, and quickly look at the coin door to see how many tickets fly out. That's a winner for kids today. Or even better for the 20 somethings, is plunge the ball and quickly look at the backbox to take a Kardash selfie and post it on fb or instagram or whatever.
