Hi Roberto,
thank you for your reply to my short review. (A more detailed and longer version will appear in a magazine within the next weeks. There I will explain that the chapter with “game engines” is in fact as you say the most interesting part of your book.) I am not surprised to read that you did not know about the final selling prize of your book. (I experienced a similar “surprise” with my first book on David Lynch). But as you would agree: the price politic of Springer contradicts the meaning of your book to be a “introductory book”. Anyone see it would guess it is one of Springer’s (often justified) high prized science books.
best
Stefan
