Quoted from aeneas:but because it proved someone could successfully (re)make pins on a smaller scale. So when JPop announced he would do it, there was less doubt he could.
This was brought up many times in both Jpop and Skit-b threads, pointing that "Gene did it" so they could also do it. Many people would tell me "it was exactly the same, it tooks years, we paid in advance, they built it in a warehouse, everyone got their game".
Knowing what we know now, about all the parts and pieces Gene had sitting available to put it together, none of those situations are similar at all, and in the case of jpop and skit-b, fraudulent activity was perpetrated on the pinball community and how do you protect against that if it was never even considered possible.
