I loved it, solid Deus Ex gameplay, sneaking around, taking guys out or avoiding totally, breaking into people's apartments, reading emails, climbing up places to access secrets, solid missions and environments, great atmosphere and details. DLC worth a punt too.
Only thing is, one main hub this time, however it does change over the course of the game (time of day and other differences as you go on). The story feels a little unfinished, but I wouldn't say this was any less of a game than HR, doesn't feel short or anything, just unresolved plot point that maybe a DLC or sequel would have addressed.
