A few chapters in now, finally got a sword for good. It kicks ass. The entire world feels smoother and more organic. The blend mechanic now works with any crowd of 4 or more. The cities aren't locked into separate districts, but you get more viewpoints as you go through the story. Character development makes more sense now as well.
Nothing particularly new, but everything's done better.
Also, stabbing two guards in the face at the same time makes you feel badass.
