The game was a bit shorter than I was expecting - it took 12hrs with a mix of action and stealth. It's a bit disappointing after Deus Ex: Human Revolution, which was a similar sort of game but twice the length. That said, it seems like it will have a lot of replayability. Plot-wise I felt the game fell apart a bit towards the end and the impact of your choices wasn't as significant as I was hoping.
