I'd like to add my two cents worth although it is probably only worth a penny. This is a hobby that is driven by nostalgia. I'm in my 50s and growing up was exposed to pinball everywhere. Bowling alleys, skating rinks, gas stations,convenience stores etc. Pinball was everywhere. Fast forward 35 years and you're hard-pressed to find a pinball machine on location anywhere so if you want to rekindle your youth then purchasing one for home use seems to be your only option. It only makes sense that today's manufacturers are putting out themes that appeal 2 people who can afford the games today. Twenty years from now the generation that will be able to afford a home use pin would probably more likely spend their money on a retro video game system to play fortnite. It seems to me it's not so much about the theme as it is exposure to pinball in general. Pinball won't go away all together but it will need to adapt to survive. Pinball has a storied history of Peaks and valleys over the years and I think we're fortunate as collectors right now to be experiencing an uptick in interest. More manufacturers, more new games,= more intrest. The theme of the game won't save the industry but getting more hands On The Flipper buttons May.
