Mr. Gygax, I humbly offer up a question to thee:
Back in "the day", Judge's Guild material was pretty much official D&D/AD&D. In addition to JG's contributions, however, I remember plenty of material by plenty of other companies that declared themselves to be suitable for use with all major fantasy RPG's, or something to that effect. A quick look inside these books made it clear that "all major fantasy RPG's" meant "AD&D." Occasionally a term would be changed ("strength" becomes "might", "hit points" becomes "wounds"), but it was obviously D&D without coming out and saying it. I was just curious if this kind of thing got TSR's legal hackles up, or was it overlooked or even encouraged? Of course, I do remember the stern warning in the DMG against using unofficial material, but was there any non-TSR/JG material at the time that caught your fancy?
