Likes: Neat way to introduce setting. Introduction and key concepts are on one page, followed by several 1-page essays (a place, a person, an adventure location). I also liked the quick character concepts with a sentence or two for roleplaying, they were are very well done. The illustrations are simple and line-drawn but evokative.
Dislikes: It might be a bit too short. The section on magic is one page and gave only a few suggestions; I felt I still needed some advice on how to stage magic in the setting (or maybe my frustration was more with "this is your setting, go play" style of book that needed a couple of examples for different levels of magic?). Although I liked the many plot hooks and one-paragraph adventures, I wanted something a bit more fleshed out (these last two sentences are actually a "like" -- it left me wanting more rather than feeling too frustrated to continue).
