I myself like old school coin mechanics of adding a quarter or such to start a game. Some pinsiders will never understand this but the quarters in your pocket and going to the arcade when you were young was a great feeling as a kid. Few EM pins I see have the coin slots working and just me but that loses something. I still like the pin but just missing that part of the feeling you got as a kid.
So do you prefer if you could have the coin slots working? Free Play or do not really care either way?
