After the game really starts easy and interesting, the enthusiasm ebbs quickly when you no longer progresses without costly in-app Zukhäufen. Buildings can only develop after a few days when one has some extremely rare items. To get in the game, however, this is increasingly unlikely and almost impossible with increasing playing time.
Who is willing to pay one or two euros for the game, will have fun for a while. For players looking for a free game, but it is completely unsuitable.
