It's the terrible green screen that makes it for me.
Also, I forgot to mention the best part of the steaming pile of Mary Sue. You see, the author, Colin McComb did
a bunch of stuff after that book, including some great Planescape stuff and, of all things, Bogleech's beloved Misfit Monsters Redeemed, which could be considered the diametric opposite of that crap pile.
Of course, the book was Mr. McComb's first design work and he's since apologized for it profusely.
