Postcript: I found what Dave N had to say about it...
Q10: What future products were already sketched out and or near completion at the time of GDW closure and would he consider bringing them out under the Quicklink banner (after some modification due to MJD's efforts)?
A: Before I left GDW to come down to Knox I asked Frank if he wanted me to leave Regency Combat Vehicle Guide for them to finish the art and typesetting, and write the manuscript for Regency Starship Guide, or to do the typesetting, art direction, layout, etc., for RCVG to guarantee that it got done and published. He chose the latter, but I was going to write RSG for GDW after I got down to Fort Knox. I was working on it on my ex-GDW Macintosh in my office down here in Radcliff in the evenings, but about a week or two after I arrived, Frank said forget it, it would never get printed. That would probably have taken a couple more weeks to finish. Loren had a lot of clipper modules and cutter modules he was fiddling with, but that would take a while to pull together. The only other thing was the “Into the Belly of the Beast” Epic adventure, which was where my heart was at in a lot of ways.
I would consider bringing them out, but am not in a position to make any promises as I write this. It would take a while for me to remember how to get into that Mac, never mind remember what I was doing.
