The Last of Us and Walking Dead are not outliers, though. Those are multiple award-winning blockbuster games.
I'm sorry if I can't list enough examples of others due to my lack of movie watching obsession, I tend only to watch a handful of new movies a year and the odd TV series, though this year has been mainly Anime. To discredit the massive audiences of some of these creations is to discredit your own argument, you're removing data to suit your own vision. Granted, I can't deny that white guys are the protagonists of a lot of games, ignoring the ones that don't let you create a custom character of course. Even Last of Us swings back to Joel's POV at the end which sucked after playing as Ellie for the real highlight stint of it - I really hope if they do a sequel it's about her a lot more.
That said, I don't think there's many people looking at CoD:Ghosts and its ilk and thinking, "yes, that is an intelligent and realistic story of human nature in all its colours." It's a bit like calling out Waterworld on its misogyny when there's a shedload of other people it's diligently trying to insult with all its might.
I also think Michael Bay should be stopped before he ruins anymore 80s IP, but that's beside the point.
Also I generally avoid Tumblr for most of the hate speech quoted above. There's a lot of bitterness in that strange, little site, and the SJW movement is headache-inducing.
I haven't heard much of Guardians, friends tell me it's great, but I dunno given one of the cast is a raccoon and it's one of Marvel's more obscure works. Will probably translate to a good movie on that budget regardless.
