The other set of rules FADAD derives from is Advanced Dungeons and Dragons (AD&D). In my opinion, the strengths of the ancient and formidable AD&D role playing system lie in its lists. Its many tomes contain seemingly endless lists of detailed magic spells and monsters. However, I find the basic rules engine displeasing and an impediment to fully expressing myself in role playing. Like many others, I have turned to FUDGE as a sensible, basic, rules system. In converting AD&D to FUDGE, I try to keep the strengths of each system intact.
Of course, AD&D is not and has never been a static rules system. FADAD is not strict in the rules set it takes from. I would say it floats somewhere between first and second editions. I would also hope there is some of the spirit of the original, blue-book D&D in it. I have no experience with Player's Option accessories, nothing from that line shows up.
Note that FADAD is not meant to be a universal adaptation of AD&D
to FUDGE. There are a number of rules and concepts which do not come from
either source. Its just stuff I like when I am game mastering, so I added
them to FADAD.
Any deviation from this standard found in FADAD is caused by (a) using a Micro$oft browser or (b) psychotic delusions in the reader. Actually, the two tend to go together. Section headers are denoted four different ways:
