By not holding Stern or JJP to a higher standard, we start making these sorts of things ok. They're not ok. Now, it's not a major flaw that will be noticed over time, but someone in the factory should have pulled the playfield when it was damaged and a new one should have been used for shipping.
If I bought a brand new cell phone and the back casing was gouged, I would hardly ever notice since I put a case on it, but it's not ok for a phone manufacturer to let that sort of physical damage go out.
Yes, damage like this was more common in the 90s, but those were commercial games primarily. With the home market being so large, tighter QC needs to be in place.
I guarantee you that a playfield with damage like that would not have left Spooky's doors, and his margins are MUCH more thin than what Stern works with.
Now, it might be unreasonable to expect a whole new machine from Stern, but I would expect that they will try to make it right in some manner. Maybe some freebies or accessories. But this should be made right and not just ignored.
