This game seems to consistently award stealth options, non-violent means more so than lethal ones. A refreshing change.
As I mentioned Human Revolution awards stealth options greater than lethal ones. But I must say this in no way detracts from the lethal approach.
It has vivid open world environments, a highly immersive game with great coloring.
The in game videos are splendid, with a lot of work having gone into them. Especially at the end of the game, it's multiple endings videos.
A negative point often mentioned in reviews is the long load times. However If you play it on medium-low settings, which I did out of necessity than the load times are only a couple of seconds.
It is a bit easy, but it's length makes up for that short coming, especially by it's replay worth.
The voice overs are all excellent. Character has many options to customise. The game involves moral choices. And importantly usually many different routes to reach an objective.
The game is of substantial length, clocking in for me 29.4 hours, without reading all the e-books in the game, this game can easily take you into the 40-100 hour mark.
Overall, Deus Ex Human Revolution is a very well balanced game, not only to the genera but in it's totality. Finishing the game one is left with a sense of completeness.
