You just haven't pounded that soft crappy wood flat yet.

Since my games are older games I never seen a badly dimpled playfield till I went with a buddy to pick up a F14. The seller had a Metallica that looked like somebody beat it with a ugly stick.
I have said before my Gorgar with thousands of plays has missing paint, planking and plenty of wear but not a single dimple. Everyone responds "That games slow, it doesn't have ramps and no airballs". I always say then why does my CPR's look so good that do have ramps and air balls?

We will never come to a dimple agreement. People with dimpled playfields will say it normal. People with no dimples are called idiots because they don't believe the "it's pounded flat" theory.
