Oh man Jim, did you have to use that image? Every time I see that image of the Walking dead game, I think of Goof Troop.
Particularly Pete and his family. It's really, really hilarious that the weird shadow from the art style does that, because practically speaking, I don't think she should have a giant black spot around where her nose is in that particular lighting.
But on topic, I do agree with what you said, as well. I don't think children as where this ends, though. I see this also when people add race for the sake of political correctness. Like when they add a black guy to a game/show/movie who's only personality trait is hes the black guy. Summery: the Entertainment industry (all of them), think we are stupid, and they will use the most basic of things to try and create the illusion of depth.
