It'd be interesting to see a new pin that would fit into a place like Round One, which draws kids, teens, and college students. Stern pins do draw people at barcades, at least they do here in Seattle where pinball is still a "thing". If pinball were to have a future on location, I think some primary goals would be:
-Increased simplicity and player direction
-Better build quality
-More humor/charm/style
This is mostly anecdotal evidence from going to barcades with non-pinhead friends, or watching other people play. They beeline for a theme they recognize, they lose quickly, and then spend the rest of the night playing Zeke's Peak. At best, I think most people approach pinball like a novelty, or a slot machine that doesn't pay out, and at worst it's just a confusing, or even annoying waste of money, and finding a way to merge the novelty aspect with a game that actually draws them in seems challenging, to say the least. Pinball seems to exist in a weird no-zone between carnival-like redemption games, video arcade (or console) games that require skill, and apps like Monument Valley or Peggle.
edit: again, this is just anecdotal observations
