What's strange for me is despite all the new games being sold, I haven't bought a single game this year, new or used. That's unusual. The last new game I bought was Ghostbusters Pro. Before that was a Medieval Madness Remake, and that isn't really even a "new" game.
When I have bought games I've been buying older B/W titles and older Sterns and running them. There's still strong demand among players and the general public for older titles. Keep in mind that to a lot (if not most) of the general public, any pinball machine is "new", even if it is a 25 year old B/W title.
I also have some friends that are willing to buy new games and run them at my locations, so that has saved me from buying new. But in each of these cases I would not have bought a new game anyway.
I've bought a few used Sterns over the last couple years at reasonable prices, but they haven't appreciated in value as in the past, probably due to all the new games being released. A couple of them have dropped in value and a couple have held steady. I'm not complaining, just an observation.
I'm not saying I'll never buy NIB, but I certainly haven't been doing it lately.
