Query: A decent guide...when it was published

Let's face it. Strategy guides for MMOGs are nothing more than an exercise in futility. By the time the guide goes from the editor's desk to store shelves, the entire game could have been redone. A few months later, the strategies described could be unrecognizable at best.And nowhere is this more evident than with Prima's strategy guide for Dark Age of Camelot. While a worthy reference at the time, subsequent changes have rendered much of the information in it useless. New spell lines were added, classes were rebuilt, entirely new zones and features were added. But the guide stayed the same, unable to update.In the first month or so of this game, I kept it as one of my most prized resources. But the inescapable flow of time has rendered it anything but. Unless you're sending this book into the past via a time machine, do not bother purchasing it.
