I think this is a great idea, but i have a couple of suggestions for an update. The mayor rating drop definitely needs to be direct. Also, the water pollution needs to be off the scale. If you put this on a river, it needs to trash the whole river.
Got a 10 from me! I've been waiting for a nice church like this. If anyone could make a nice landmark style cathedral, that would be awesome. I've been making a city in the london region and have been wishing for St. Pauls and Westminster. Alas, no such luck yet.
