The closest thing to a dystopia is after a nuclear bomb detonates because there are people who want to help each other and there are people who want to take advantage of the kind people like in the game. The citizens would be alerted about the bomb and have little time to get their supplies to take into their bunker or safe zone. Most of everyone is going to have generators because the power grid has been wiped out from the bomb. Some people are not as fortunate to have all of the necessary supplies and some left over, so they go around trying to coerce someone out of their supplies promising to give some back. After the dust has settled and everyone is safe to leave their bunkers, everyone will see how barren the city streets are how there is an eerie feeling around them.
This is what usually happens in any tv shows or movies that try to portray what a dystopian would look and feel like to the people watching it.
