Could this book become collectible one day? It's a parody/humor book published under the
OGL in 2004 by Skirmisher Game Development Group.
Mongoose's
Slayers Guide to Female Gamers and
Slayers Guide to Rules Lawyers were subtle and tasteful.
Nuisances takes a different tact and goes for the jugular with the first sentence in the intro: "Shit happens." The content is raunchy but unintentionally deflates other "serious" raunchy
RPG material (Erotic Book of Fantasy, or whatever it was called, and that
RPG with stats for naughty bits).
It could be useful to generate some wacky NPCs or extremely off-the-wall situations, but probably not much more than that.
