Quoted from tamoore:I have a Metallica from 2014. It has more plays on it than any other game in my arcade over the past 3 years. Dimples aren't something that I notice, if they're there at all.
My Metallica is a little over a year old now and it is FULL of dimples. It looks like surface of the moon... I don't think it affects game play but def dimpled.
Curious since yours is a bit older if there was a change over the years that the newer play fields are dimpling now...
