Who throws a PS4 like that? Man, that stinks. Well, it led to Yamano becoming a gamer, so that was good. Too bad that the electronics man kinda scammed him with things he'd never need.
I think I get his motivation for playing. He's always been a good hunter, but he doesn't like killing things. So now he gets to hunt, without killing anything. And he's still good at it.
But I wonder, what made him so unsociable? It seems he was always like this, but his wife must have been quite the person, right? It seems his own family understands at least, that he can be stand-offish. So they didn't force him to live in the city.
