I don't think any of the Product Development staff knew that Gary was being paid royalties while we were denied them (having to sign "work for hire" statements as a condition of employment). That's news to me, reading over this topic. I think we sort of assumed as a president of the company, his salary was such that royalties per se were irrelevant. So it's interesting to discover that he was being two-faced about the royalty/bonus situation when it came to the later hires.
I have heard about this podcast series and really need to try and access it! I know I was interviewed for it years ago, as was my wife Mary (see pic in the Dungeon Hobby Shop, 1981) but we were never informed by the producers as to when these came out or how to find 'em.
