Quoted from Palmer:You own one pin. When you go to play pinball at home, you play that one and only that one. Someone that has a dozen pins can play each less because of the variety. Also if you want to purchase a NIB game at release, you are basically buying a game you have never played before. Some people get a NIB game, play it and don't like it as much as they thought they would...or decide they want a different trim level. They see that they can make some profit because there is a subset of people in our hobby that will buy games no matter the markup. Just saying there are other reasons why games sell with lower plays/less time of ownership.
I have 10 pins at home and picked up a Godzilla Pro 2.5 weeks ago and already have 250 plays on it myself. There's probably another 150 games put on by friends and family. If someone buys a pin and plays it only 25 times they aren't really a pinball player and bought it for other reasons.
