Like I said, I play in games where it is just overlooked. But people act like people in our game. With the same characteristics of regular people. Greed, pettiness, love, and desire. Fantasy societies are also sculpted after real world societies. Why? Because that is all we know. So we combine what we know, a touch of ancient Egyptian with a smidgeon of rural European Renaissance, and a healthy dose of Voodoo. But those all come with preconceived notions. And one notion is that when people see something they have never seen before they have a visceral reaction: worship, adoration, envy, fear, hatred. To pretend that they are not petty is to pretend that they are not people.
