The obvious solution is to treat these like all other collector toys and keep them in their original boxing as long as possible. Maybe some folks can test this and season their NIB games for a few years in the attic and let us know if they wear any differently.
Alternatively in the same way a new car is protected from bugs and sand debris from driving, maybe just dip the thing in plastic to protect it. Seems like a market opportunity for a savvy aftermarket specialist.
Now back to yelling at kids to get off my lawn and shaking my fist at the sun for being so damn bright.
Joking aside. I can't think of a single thing that is as good today as it was years ago, and all of them are more expensive. IMO play it, enjoy it, and do your best to make it last as long as possible, but its just not worth it to expect it at any price in today's world. Consider too that even if its not 'seasoning' the wood, it could be that the new growth trees available today, simply didn't grow as slowly and won't ever be as dense.
IMO I'd rather try to spend time on what I can enjoy and appreciate. Sure it sucks, but not worth more than a passing notice.
