I am not really sure what you do. If someone figures it out, please let me know.
Currently we are examining adding a second floor to our house just for pinball. If not that, then we will likely move to something built specifically with pinball in mind.
My real problem is I am not sure how many I want room for ultimately. The colection grows organically and the next thing you know you need more room. 1 turned into 2 which turned into 12 in 12 months. Things slowed for a bit and then I started sharing them on route. That meant I have more room but long tern plans that they will all come home at some point. I now have lost count and stopped updating my colleciton on line, but still have a long list of wishlist games I want to have in my ultimate collection.
In my long range plan I think I would like a house out of town slightly where I can have 100 games set up in a sweet underground bunker. From the outside it will appear to be a 1000sqft ranch of modest size (besides pinball we dont need much space), but once you go to the basement you realize that the house on the hill is hiding a magical room of pinball.
In short, when I currently run out of room I guess I buy them for the future. I give to relative to store and play. I put them on route for others to enjoy. I offer them to any trustworthy locals to shop out and enjoy till I have more room.
Yes, I have a disease. However, I have gained acceptance with the disease and as I age I realize life is fleeting and if I have my bills paid, am laying plans for the future sustainability of my family, and am able to love and share this hobby (obsession) with my wife, then life cant be much better!
