Tabletop minis games are certainly an attraction for the younger generations. I imagine some of them get burned out on constant video gaming, as I've regularly done in recent years. Looking around for a related, but different, hobby to fill the burnout holes.
There has not only been a resurgence in boardgaming in general, but also a boost in tabletop wargaming companies' sales. Yes, even ye olde map & counter wargames.
For example, GMT has been swamped with orders and new game pre-orders (P500) for years. They have new and ready-to-go game designs, with over 500 pre-orders apiece, sitting on wait lists for well over a year before going to the printer and getting distribution. They've been having a hell of a time getting their warehouse & distribution capabilities upgraded to accommodate the increasing demand, so the production is getting delayed. Because they can't keep up in the shipping end. After new titles are finally done & available, they often sell out after a handful of months, another P500 reprint pre-order goes back up, and the wait starts anew for those who missed the print run.
It's not uncommon for designer board & war games to require multiple print runs just to keep them stocked in stores nowadays. When I came back to the hobby a few years ago, after sliding away from it back in the 90s, I was surprised at how many titles were quickly going out of print. It is still happening, but some of the manufacturers have wizened up and increased their print runs & frequency to meet demand. Not all, mind you, so something that just came out may be out of stock a couple months later.
All this yammering was to point out that tabletop gaming has had a recent renaissance. Which includes wargaming to a lesser extent. It jumped so quickly that the industry is still adapting to the spikes in demand. Co-operative/Solitaire tabletop games are huge right now.
I guess people are feeling the urge to 'unplug' and stop staring at their tvs and monitors more often lately.
