I used to think those books were a cool idea for building up PCs -- but after using them just a bit, I realized that it always felt like the characters story was done before you actually played the character in a game... The system generated so many twists and turns in a character's backstory, it either became hard to reconcile them all together, or they developed obvious motivations that would conflict with playing adventures. A case of covering all the bases, instead of the bases that needed covering for the adventure/campaign you were actually playing.
You could strip the results down, but then you've spent a lot of time to just settle on a couple of ideas.
Using them for NPCs, on the other hand...
