I'm amazed that Prima hasn't gone to an online supplement for MMORPG guides seeing as how MMORPG's rapidly change after release.

Basically like when you buy the book you'd get a code. You register for their forums and get access to the section for that game.

Then as patches come in and info from the guide is obsolete, Prima updates that info online for you to check.

Oh well, guess they really only want to make a quick buck though.
