Thinking about the timing, TWD was released not long after it was announced that Stern got the Kiss licence.  JPop took his non playable prototype to Chicago expo I think (oct 2014), only to have the licence granted to Stern just a few weeks after.  So the timing is right that Borg could have been given KISS immediately after TWD, with instruction to get this done ASAP.

KISS would have wanted to rush out the game out to coincide with their just released album - something that Stern probably explained to the KISS marketing people was not achievable by JPop.  Stern probably passed the game to the person they feel is their fastest designer - the master John Borg.


...This has to be a KISS machine!
