I would have thought the Chineese would have been faking KISS merchandise for years, thus keeping Gene Simmonds and Co busy to the hilt with cease and desist etc, if they have bothered because that in itself would have been a fulltime job.
One consideration, every mod made for a Kiss pinny makes the game more desirable and therefore Stern sells more and the band gets their cut $.
So maybe they will leave the small $25 to $100 mods alone.
Plenty of people made small mods for ACDC and no one ever cared.
Maybe Kiss are too busy looking after their other 3,000 licenced items to care about a reviving pinball industry.
Time will tell.
