Ok, so I had the perfect city, with plenty of food, hospitals and survivors. Then, one of my leaders decided to become the preacher of the city's church. Unfortunately for me (and for all my citizens), it was the Church of the Chosen Ones. Everything seemed normal, until one day, I was notified that two of my survivors were against "the church". I ignored them, and my preacher decided that they had to be sacrificed. After having them killed, the church members decided to celebrate their "holy victory"... first, their celebrations lasted one day... then, all my survivors stopped working, and rejoiced themselves in a massive celebration, that ended in ritual suicide. Thanks Church of the Chosen Ones, you destroyed my city! BTW, excellent game!
