Just thought I'd drop by seeing as this game holds a special place in my heart... it was the game of my youth, sat next to a Bally Star Trek in the foyer of a cinema in Rotherham, England... I used to play the Star Trek (which always had 4 players playing) and win replays and then sell them to other people in the queue at 2 for the price of 1... then I'd use that money to play the Paragon, which was 10x better to play than Star Trek, but 10x harder to get replays... I'd always leave myself a credit or 2 on Star Trek and go back to that when my game was over on Paragon so I could rack up more replays, sell 2 off and go back to Paragon... keeping a track of whos credits were won by who was surprisingly easy as a kid... this was my routine for several months... the op was probably confused why there were more games played on Star Trek but more money in Paragon
Needless to say, when the concept of actually owning a pinball came to my mind, Paragon was the game I tracked down... and found... and still have...
