IMO, although I enjoyed HR, it can't touch the masterpiece that the original was.
TBH, too much of the new game felt like a watered-down by committee set of safe options.
For instance: the fact that you can upgrade pretty much everything, and certainly everything worthwhile without much bother. The original really forced you to choose by closing off augmentation options depending on your choices. A much better system that really linked different builds and play-styles well.
The background world and plot was much deeper as well, as were the choices you have to make. You really had to pay attention to the dialogue to suss out the details and consequences then. Also, the locations/hubs were more varied and interesting. Too many identikit offices/corridors in the new one. Also Hong Kong >>> Hengsha.
The multiple endings were handled much, much better in the first one. There were consequences for your actions in the last 1/4 of the game or so, not just "push button A for ending 1". Bah!
The voice acting was better this time around by a far chalk, mind. Though I did prefer the original sound-track, and was disappointed not to hear it reprised.
Oh, and too much hacking! Far, far too much. And far too many identikit computers in identikit offices on identikit desks to do the hacking on!
The first DE still stands as a modern meisterwerk, and the new one, good as it is, can't compete.
IMHO, of course.
