Dungeons & Dragons has gone through many revisions. We will
concentrate on three (3) distinct categories for the Dungeons & Dragons series.
The first categoy is the Basic (B), Expert (X), Companion (CM), Masters (M)
and Immortal (IM) series. In this series, there were acutally three different
releases of the rules and module. This makes up the bulk of the D&D product
line. Then came the Challenger series, an attempted to revitalize the
Dungeons & Dragons market. And finally, the Mystara series, which was an
adaptation to the Advanced Dungeons & Dragons rules set.
I know there are the "small booklet" series which started the whole thing, but
I am going to concentrate on where I am most familiar with Dungeons &
Dragons.
The following is a checklist of all the products that was introduced for the
three categories of the Dungeons and Dragons life.
