If your first play through involved killing people, try completing the game non lethally (except for the boss fights) for an achievement.

I was also recently listening to that soundtrack. Kind of excited to see this thread, sometimes I think I'm the only person that loves this game.
There were several places during my initial run-through where I found myself having to grab a pen and paper in order to keep track of things like small AI conversations in passing which lead to new side objectives.
The internet joke about the original Deus Ex is that every time it’s mentioned, someone reinstalls it, but I think this just convinced me it’s time to replay Human Revolution.
It looks like in the sequel they're using that even more to indicate the golden age renaissance of augmentation is fading away.

Also McCann is coming back for the score which makes me happy. I still have this soundtrack and listen to it often.
Finally, off the new trailer, anyone see the Megan Reed parallels with the leg augmented guy?
I am really looking forward to the next one!
