"Is the Fiend Folio (1e) ridiculous, stupid, inadequate, or perfectly serviceable? I've been looking at my copy with an eye towards writing a review one of these days, but I was not part of the 1e generation to whom it was soemthing new at the time."
A lot from column A & B, a bit from column D. It's easy to point to all the goofy stuff (very easy) and laugh the whole book off, but to do so is to ignore a lot of awesome material Death Knights, the Githzerai and Githyanki (all created by SF author Charles Stross, btw), the first write-up of Lolth, Slaad, and the Drow. Yeah, the Drow made their first non-module appearance in the FF.
As far as I can remember (bearing in mind it was over 30 years ago), a lot of the stuff in the FF just puzzled and confounded me. I was familiar with White Dwarf, which was a generic gaming mag at the time, and knew a lot of the material in the book came from the magazine, so I just put it down to it being "British." But even then, I knew it was a window into a different take on fantasy, one I really didn't grok from my middle-class American POV.
(Looking back on it, I think some of my confusion was due to the utter lack of overlap between D&D players and stoners in my teenaged years. Classic '70s stereotypes be damned, all of the RPGers I knew were in ROTC and definitely not stoners. Probably to our collective detriment.)
