Finally got my hands on Deus Ex: Human Revolution and currently playing it on 360. As a huge, huge fan of the first Deus Ex, I've been cautiously excited (emphasis on cautiously) at the prospect of getting another entry in the series that wasn't as awful as… Project: Snowblind, and you know what, I think we may just have gotten it.
(I bet you thought I was going to say Invisible War, weren't you?)
I had basically given up all hope that we would ever get another game like the original, but after putting in a few hours today and getting through the first two major "areas", I've got to say that so far I am incredibly pleased and happy with the way the game has turned out.
As is proper, I've seen plenty of opportunity for player choice between combat/stealth, and I haven't yet found a scenario that I wasn't able to complete in the way that I wanted. Although the game is mostly first-person, it's far from being a standard first-person shooter and both requires and rewards thinking and exploration on the part of the player.
In terms of style, I'm playing as the ultimate Boy Scout at the moment… I haven't killed a single person and every major choice that I've come across (at least, that I'm aware of) has worked out in a mostly positive way. Well, I guess I might have knocked out a detective who was minding his own business in one of the upper floors of the police station, but that shouldn't really count.
It's been great, great stuff so far and I've been enjoying every moment of it.
Although I'm still quite early in the adventure, based on what I've seen, I would have no problem recommending this to anyone. In fact, the only word of caution I would share so far is that it seems hacking plays a pretty huge part in getting past obstacles. That's to be expected, but I think that maybe the game puts a little too much emphasis on it too early. Luckily, I put some points into the skill right away, and my advice would be that most players do the same.
(Thanks to @SidShuman for the initial tipoff.)
