Maybe my area is different, but $1 per play is going to turn off a lot of people. I personally wouldn't frequent a place charging $1 a game and I only play on location. On new titles sure, but for pretty much anything else $0.75 a game will probably bring in more volume. Heck at a truck stop I like to go to, the most popular game is Metallica simply because it is set to $0.50 a play. I think your prices are on the low end of what I see out on location, with the level of maintenance you are talking about it is unheard of.

I think $0.75 per game on everything, but keep one priced at $0.50 to keep the cheapskates playing. You might be able to get away with $1 per game on a new game if there are a lot of more knowledgeable pinball players who come in. Otherwise, the only thing that will make Ghostbusters stand out to a new player is the higher price tag. JJP's games could probably get away with being $1 when new, but even then most of the ones I see on location drop down to $0.75 pretty quick.

You wouldn't mistake a movie made in the 90's for one made today, you wouldn't mistake a corvette from the 90's with one made today. The general public would not be able to tell the difference between most recent pins and those made during the early DMD era unless the license dated the game. Pinball has evolved through deeper rulesets, but they don't look much different besides the photoshopped art.

I have seen many examples of people turning their noses up at paying higher prices for pinball. Even had a guy ask me why I was playing the GOT LE when MET Pro was a quarter cheaper. You don't see the average person complaining because they just won't play and that would be the end of it
