Got UC3 for Christmas and have only played about one hour. I'm at the beginning of Chapter 6: "The Chateau."
So far, I am loving this game. I played UC2 a few years ago when I got it for Christmas and absolutely loved it due to the story that went along. This iteration is just as good, if not better, than UC2. It's like watching a movie!
Also, because I played UC2, I am moving through the game much faster this time around since I am accustomed to the controls and what to look for. I noticed I was picking stuff up much quicker.
