I agree. I know a friend (or maybe even several, it doesn't seem uncommon in this hobby, but is usually shorter term which I find acceptable) who has many games in this situation and although he is my friend it did make me really sad as there is no "end year" in sight, been there for years upon years and likely will be there for years. I know they are just inanimate objects, but it is depressing to see history like that just sit around taken apart in the dark the same place every day with no change, every July 4th, every Christmas, every December 31st (when the rest of us are having parties or enjoying our machines with family or friends around these specific times), just in storage units or in storage elsewhere.
I come back to the thought a lot, don't know why. Just makes me sad/depressed.
I'll be storing some of my games myself since I've run out of room, but mine will be stored in anticipation of opening a pinball museum one day (so, with purpose, or at least a reasonable optimistic excuse) and I will also be rotating my collection out through it so everything gets played from time to time and loved. Also most of it will be heated in the back of my basement. They can still hear what's going on at least.
