The writing in this game is what is non-standard; it stands out really, really well in comparison. So, if you're worried about boring and tired tropes or stereotypes and that's why you're looking for more and more extreme genres (I went through the same thing tbh), then you should give this game a try because it breathes new life into all the classics imo.
BTW, for anyone doing a drive-by on previous comments, you don't have to avoid the patch just because it unlocks dark stuff; none of it is forced on you and the way your character behaves is your choice. And every dark action comes with an obvious 'warning' so to speak, so you don't accidentally stumble into it either unless maybe you aren't a native english speaker or something like that.
