Excellent, logical and realistic game system. But only after you took the time the read every rule. Until then, the game is extremely hard to understand, even to read. It is not an option -- not even for a player -- to read only some rules and start playing.
The magic system is excellent and gives possibilites very few other game do -- however, the chapters about magic are the most complicated.
The book is extremely poorly cross-references, the table of contents is ridiculous. There are no bookmarks in the pdf.
