A lot of people have been saying how bad the guide is, which I agree with quite often, but I thought I'd be the oddball and say GOOD things about it.
It does tell you how to become the special roles. It has good tips for character creation. It fairly accurately describes what the advantages and disadvantages of the different Roles and Clans were. It'll get you through the game, the walkthrough is accurate enough for that. All of the tips in the advice sections are accurate and rather good. The maps are all 100% accurate. The boss and monster defeating tips are all very good (basically, it says Mantraps are EVIL!!! I HATE those things!!).
Come on everybody! Join in on the good points! Well, as long as it doesn't overshadow the bad points
