I have tons of stuff I've never actually played or have no interest
to play. But I don't consider them bad buys, because usually they
have all the great fluff I want. I value good "fluffy" material over
the so called "crunchy" bits every time.
Stuff I think was a horrible waste of my money include:
AD&D 2e Arabian Adventures. I never really cared for AD&D.
It just turned me off. But I was interested in playing an Arabian
game, so I bought this book. What a waste of money. It had
nothing but rules in it. I was expecting setting material and GMing
advice on how a Arabian campaign would be different. Maybe I
expected all the wrong things, I still wonder if there was a companion
book to this, kinda Core Setting book, which I believed this to be.
I still ran that Arabian campaign but it crashed and burned pretty
quickly. Not that I blame the book for that, mind you.
Alternity's Star*Drive core setting book (was that '*' supposed
to represent something? I've always wondered). Now this is a book
that was full of both "fluff" and "crunch". But it was just so BAD.
There are others, but these are the ones I remember from the top
of my head.
