I have been playing this game since july 2016. I like the game and am having great fun with it. I always spend a bit of money in "free" games when I like them. I will continue to do so as it pleases me. Expansions were my main purchases in this game, in my primary city I have all 23. In my secondary city I do not have a single one, and will never have one as playing that one without diamonds was the whole reason I started it.
I must confess that from day one I thought the prices here were a bit on the high side. The money I was willing to spend did not go far here. After this update, it won't do anything but get me some cultural buildings that I will just need to delete in a few chapters. The chances of me spending additional funds in this game just dropped.
