The main reason why we publish virtually no playing aids or adventures specifically for the D&D game is that people generally don't contribute manuscripts on that game. And that's because the D&D game doesn't really lend itself to expansions or variations like the ADVANCED D&D game does. As we've said many times before in many different ways, the D&D rules are more like guidelines and suggestions, and the AD&D rules are more like actual rules, of the unbreakable or unstretchable sort. In the case of the D&D rules, it's difficult to suggest how to do something in a different way when there aren't any hard and fast rules on how to do it in the first place. The AD&D rule system is much more detailed and more specific to begin with, so altering it or expanding upon it is easier to do.

This is a good time to point out, for those who are still misled by the similarity in names, that the D&D game and the AD&D game are not structurally related to one another. Many of the rules concerning specific topics are vastly differenmt [sic] in each game. It is not possible to translate a D&D campaign into an AD&D campaign, or vice versa, without losing an aweful lot in the translation.
