If you think the citizens in city builders are grumpy and needy, try pleasing a bunch of jealous Roman gods

If there's one thing that can ruin a beautiful and efficient city, it's the people who insist on living in it. Build them shelter (well, command them to build themselves shelter), and they'll want a convenient marketplace to buy food. Make food available to them and they'll start complaining that they want more than one type of food. Let their neighborhood flood and next thing you know they'll be asking for ways to respectfully dispose of the bloated corpses of the dead. There's just no way to please them!
