Query: It's not that bad

It's this simple.. If you're new to role playing games or are less then lever 30 and don't have to be spoon-fed information, buy the book. If you're over level 30, been playing the game for a year or have to be handed information, then don't. I personaly find the book priceless. However, you may have to do a little digging to find what you want until you get use to the layout.
