Anyone else getting a feeling this game was heavily inspired by the book The Road (By Cormac McCarthy)
It features a man and his young child(who was born after the world went to shit), and they are scavenging to get by. Obviously the biggest addition is some kind of creatures.
Personally I think this is a fantastic idea. My biggest hope is they keep up the whole scavenging aspect in this game like in the trailer. One of the best part of The Road was how the Father and Son were desperate for food and other supplies. I can't wait to see more on this.
