Quoted from PW79:Foil hat time
Maybe Stern told TPA to choose between WMS/Bally games or Stern games, in an effort to sabotage CGC sales in the real world?
Various members here state often TPA was the gateway drug which led them into pin ownership.
Demand for RBION increased after the TPA version & I'm sure other games gained popularity from TPA as well.
Or TPA sucks & folks quit buying the shit. I know that's what happened with me.
It wouldn't be the first time Stern stuck it's thumb up TPA's butt.
They are the reason the VR didn't get into the original game. They wanted to focus on the crappy mobile VR market, and stopped TPA from doing the conventional VR.
