Finally trying out Dishonored..
There's not much insight I can give since I think nearly everyone else here has played the game already. The only thing I feel hasn't been addressed is, this game has by FAR some of the WORST voice acting and character animation of this console generation (7th.) I was amazed at how laughably bad it is. The opening murder scene was about as impactful as watching an episode of Captain Scarlet. Also, the dialogue seems like it was written by a 12 year old, especially that of the guards. The fact that they just speak about what ponces they are (when they're not just pontificating in sentence fragments of swears) does break the immersion quite a bit. The worst part is that you know they're trying really hard to come across as serious, as opposed to a game like Aliens: Colonial Marines where the actors just don't care. Here they were really trying, but I think my two young girls could do just as good of a job.
Other than that, the game does seem intriguing, although I'm torn as to how I should play, whether I do a Low chaos or a High Chaos playthrough. I'm leaning more towards "do whatever seems right at the time" and depending how I like the game and the ending I get, I'll either play again in the opposite way, or just look up the endings on Youtube.
I went low chaos when I could but I didn't let it pigeonhole me either. If I thought the route that made the most sense required killing people that's what I did. If I could sneak past them using blink or other means that's what I tried to do. If I had to knock people out and hide the bodies to avoid being detected I did that too. If I was detected I had no problem with using my powers to kill the people who saw me. I think that is the beauty of the game. There are always multiple ways to complete a mission. To get into a house, some people might knock someone out and take a key while other people never even have that confrontation because they found a way in through a window on the 3rd floor. I still got the low chaos ending even though I killed people now and then. The game isn't perfect, but I certainly had fun with it.
I still haven't played the two story based DLCs yet. I hear they are both very good and some say they are better than the actual game. I got The Knife of Dunwall in a Steam sale but I still don't have The Brigmore Witches yet. I'm kind of holding off playing the first one until I have them both.
