I can only agree with the previous, English review. In 95% of the explanations is simply reproduced what you so well already be seen from the game or the Building Information menu in the game. In addition, there is indeed information in special, designated as important information boxes such as "Without power plant your city has no electricity, so they build a power plant.". This form repeats itself useless knowledge unfortunately very often so that forces itself upon the suspicion that you just wanted to produce only text. Really Useful contained so little in the texts that you can discourage a purchase at this price, also from the acquisition of approximately 9 expensive eGuides (same content available only purely online) is not recommended.
An ideal aternative this eGuide is therefore - from personal experience - the GameStar Special Issue 02/2013 to SimCity, which offers more and better and cheaper (7.99) information on 146 pages. Here you can actually learn something to all this very well described and graphically edited with practical overviews etc.
