Quoted from Goronic:
I would guess that neither Stern or JJP directed or provided specifications to Mirco about how to do the playfields, and they got burned. I'll bet they have much better PF quality control and rejection rate after this debacle.
You may be right, but if Stern and JJP are buying specialized parts like playfields without good purchase specifications then they really are amateurs. They've had major playfield issues, e.g. ghostbusters and WOZ, in the past and should have learned their lesson a long time ago. They may be stuck with the current external suppliers short-term, but Stern, and maybe JJP, certainly has the knowledge and resources to in-source production of the single most important/specialized part of the game going forward. Hopefully Jack and Gary are embarrassed/pissed about their business being undermined, and that Spooky and CGC are able to supply superior play fields.
