In the past 6 years pinball is gaining a lot of popularity so the price gone up a lot. I am hosting pinball meeting yearly. I believe my 1st one was less than 20 people attended. The most recent one was limited to 32 people due to the size of my house and I don’t own a lot of machines. Surprisingly I had 39+/- people attended. People were having a good time and I really enjoyed. My pinflation explanation is “doubled the size so doubled the price”.
