Sign textbooks there are a dime a dozen. I would have expected in this book is that it pays special attention to the needs of a designer for games or to the relevant training of students. That basically does already, but delivers them to sign technically unconvincing picture examples. In explaining the perspective (vanishing points), there is a definite misrepresentation (parallel edges of various objects have now even a common vanishing point.) Who takes the book as a complement good sign textbooks which may be satisfied. But not far - it replaces - or a good education. Conclusion: 1-2 star as drawing school, 3-4 stars for the reference to Gamedisign = total 3 stars.
