Re: 7/10 at best.
I have only just left the tutorial, so I can't say anything about how good it really is, but I agree with this:
"* Voice acting is awful in the main"
Given how much applause the game got for its voice acting and emotions, Geralt seems emotionally detached, monotone even.
Other than that, looking very good so far, although it's one of very few games that I cannot play on maxxed out settings with steady framerate. My 4930K and 780Ti drop below 60 fps every now and again. Not a huge deal, but a tad annoying. (I expect an NVidia driver update to sort that out soon; usually they get a new one out of the door shortly after a highly anticipated title such as this game is released)
