Update: Today, I have the rating lowered since the last update consisted primarily of in-app purchases. Next, the speed has been reduced by more sense gameplay, so purchases as "Vorspuhlen" "buy prestige points" result. The game designed from now on without any additional purchases to be quite boring.
Definitely the app was once recommended. Currently however, it turns out to be more than a rip-off that exceeds the prices of high-end PC and console games far. I can only advise against the purchase.
