I think location and condition of the pins has a lot to do with pricing. In metro areas, $1/play on the newer games is OK. $.50 on DMD/SS games. In small towns/rural America, I see lots of resistance to $1/play games. $.50 DMD/SS games are OK, provided the pin is fully operable, unfortunately a rare occurence.
There remains a significant pychological barrier to $1/game pricing. Not saying its good or bad. Just saying its there. I fully realize pins are not cheap to buy or maintain. Understand the concept of return on investment. My mindset still hasn't fully accepted $1/game pricing. Am I part of the "Cheap Bastards of Pinball"? Probably.
