I subscribed to Play Meter for years, and always found the % responding column of greatest interest. It is meant to represent the % of those providing survey responses who rated the particular game (in other words, it is supposed to be a signal as to the % of operator respondents who had the game on location). I still find this fascinating, as the results of this survey show about 1/3 of all operators still have a TAF on location, a response rate that is almost two times greater than any other game on the list. And tied for number two is AFM (along with POTC and AC/DC). So, two games that were manufactured at or near 20 years ago are still in as many locations or more locations than any game manufactured since. One could interpret this several different ways [e.g., (a) operator decision not to invest in pinball and to just stick with existing inventory for the past two decades, (b) operator dissatisfaction with games manufactured since mid-1990s (c) demise of the operator arcades, or others], but it is a very fascinating trend. I can't think of any other electronics oriented product or industry where 20 year old products are still the ones most frequently marketed to end consumers.
