BT:Papo & Yo is about alcoholism and paternal abuse. That theme is central to the entire game. It's shared through playing as a young a child creating a fantasy world that allows him to escape from his real living situation, but this creation is flavoured by his real surroundings. He's altering environments he's familiar with and he replaces his father with a hulking giant monster. By day it's docile and occasionally helpful, but as soon as he succumbs to his vices he's a terrible threat to the child’s safety.
