Summary: After reading all the glowing reviews, I really thought I would enjoy this game but I was rather disappointed. While its true that you can approach the game in different ways, you are penalized for killing so you are clearly steered down the stealth path unless you want everyone looking at you like you are a maniac and getting the dark/bad ending. The problem is that playing strictly stealth can be very tedious and frustrating.
Summary: It's really fun at first but after awhile, the story starts lacking and the gameplay is very repetitive.I personally do not enjoy the game. The DLC was decent-ish but it still had the repetitive feel.
