I think it's partly things you might not have used to notice and partly because game (and movie) design as pushed so hard away from subtlety to total polarization of characters and shoving it in your face directly.

Movies are a much more mature medium and they compare to games fairly well. There's been politics in movies almost as long as there has been movies. It just wasn't always so direct--a.k.a. lame. You're no longer left to wonder about anything. Every character must be clearly bad or clearly good and even worse they make it so obvious, often to the point of straight up telling you. Shame and hate for the bad ones and constant glorification of the good ones starts from the very beginning. Good characters are no longer allowed to have flaws at all--none. The only "positive" trait allowed to bad characters is if they at some point come to the realization the good characters were right from the beginning. Then you add in the even worse level where in modern movies the good must be the preferred liberal classes, i.e. alphabet people, women, etc. The bad characters must be white men, capitalists, etc.

So what I really hate about most of these stories is they aren't a story at all. If I know who is good, who is bad, and good will be worshiped and bad will be shamed all the time--what's the point of even paying attention?
