This is a well-written game guide that finally does what game guide have been promising for years: there are no spoilers!
To clarify, there are obviously spoilers, but before it discloses them, there is a warning. Some sections are so chockfull of spoilers, they just label the whole section. However, as I just recently completed my first playthrough, I did not see any unwanted spoilers when I just wanted to find a map or information on how to woo a particular companion.
In general, the guide does a great job of, well, guiding you through the game. There is an intriguing section on party building and a system of how to spend attribute points, if you're into the hard mechanics of RPGs. The artwork and asides at the back of the book are beautiful and interesting, expounding on various aspects of the world of Thedas.
Though I love this book, I couldn't give it a full 5 stars, due to the truncated Index. There were several things I wanted to look up and yet were not mentioned at all, forcing me to brave a sea of spoilers just to find a specific detail.
