Ah!!!
"In this case, "no style" style is possibly one of the most difficult and skillful results of craftsmanship."
For some reason when I read that, everything else you'd been trying to say clicked. And while I disagree that stylizing is itself a cover-up in most big budget titles (for which talented artists were sought and hired), I am wholeheartedly with you in your non-preference for it. Yes, I recognize their talent, blah blah blah. But, no thanks. Instead, give me something which must slip over my own form before it can become truly defined (I know that sounds vague--more below).
This is why I prefer game designers who speak in terms of art direction and not those who speak of stylism. And there is a non-subtle difference. If you want to meet some artists who will talk about stylism, see Blade & Soul. The only use for realism in a stylist's world is "knowing the rules before you break them". Art direction, on the other hand, is the way in which you present a world that seems as if it must have already existed.
Ron Moore spoke of this in filming CGI scenes in the Battlestar Galactica remake: most of the space shots were filmed from camera angles which would have seemed plausible--as if a real camera rested on the wing of one of the ships. The viewers were never the wiser, but somehow the camera work in those scenes seemed so darned realistic. Well, now you know.
In Marvel's movies, heroes like Captain America never come rushing down at the camera with an over-sized mouth and large, baby-like eyes, wielding an over-sized sword as the background whooshes past him faster than the foreground. Those make for great stylistic dramatic impact in other places. But instead, superb choreography is used to illustrate seriously cool fight scenes. Well okay, you can take that same choreography and put a midget like Yoda in there--now it's funny. This explains how our heroes completed the formula of art direction in City of Heroes--your "Non-style."
CoH's designers were quite open about their direction and influences when they posted on the forums though. It was one of City of Heroes designers who used the term cinematic realism, not me. I don't want to say who, for fear of misattributing.
