Pretty the game is, though, there is no doubt about that. Personal taste might affect how much one likes the yellowish tint everything has but I found no fault in it, nor in the general art style. Though I do wonder the meaning behind the single white room in the game. It made me think of 2001: A Space Odyssey, and apparently I was not the only one. My quick search did not reveal anything definitive, however, so I guess the meaning shall remain a mystery.
DX:HR has grainy skies, too. A pretty common thing for games for whatever reason, I have found. It was not that bad, though, and often a lighting effect conveniently covered the graininess. Otherwise the game is gorgeous.
As a bonus, you frequently get to see your character, Adam Jensen, when you a hug a cover and the camera moves into third person. I very much liked this feature, even if it felt bit like cheating compared to the other two games to have such thing aiding with one's sneaking. For stealth purposes it is indeed very useful; for combat not so much. You can shoot from cover but I found it bit too clunky compared to Mass Effect 3, and did not use it for that.
Then, after many attempts, I realized maybe I should try the remote-detonated explosives given by The Explosive Mission Pack DLC. I started the fight, hugged the waist-high cover in front of me, threw four of the explosives to the boss's feet, detonated them, and it was all over in less than ten seconds.
The two DLCs were originally pre-order bonuses (and which one you got, depended on where you bought the game) and received their share of criticism. I bought them mostly for the silenced sniper rifle, which I liked in the previous two games. Having it available only as a pre-order bonus/DLC is blatant money-grubbing, though.
The 10k credits from The Tactical Enhancement Pack did not greatly affect my playthrough, although the idea of buying DLC to make a game easier surely is dumb. But the credits merely meant I could buy two praxis kits right away and for the rest of the game I just had 10k extra cash with nothing to spend it on. And two praxis points hardly made a difference. In fact, most of the game I sat on quite a few unused points, waiting to meet an obstacle that required an augment or two.
Regardless, I was glad to return to the main game and to have access to all the tools again. I think the most important augmentations one should take are the ones that allow you to get to places; hacking, improved jumping etc. The defensive passive will aid in the boss fights as well. The rest are pretty much optional in my opinion, even the social enhancer, although I guess I cannot really say if it has its uses as I never took it. I did, however, beat all the dialogue challenges on my first try. Such a cool feature those.
The fact of the matter is that such interface design works fine with the keyboard too. Developers just do not tend to optimize their games for it. Like in DX:HR, instead of clicking the small arrows to navigate the store, you can instead use the arrow keys and Enter for buying and selling. But why not have WASD and Space do it? Your left hand is already on them. And it is not like you are moving your character when shopping or talking to someone.
If you have played the two other games, Deus Ex: Human Revolution will instantly give you a sense of familiarity. The themes and factions are pretty much the same and you can see where things are going. The soundtrack is not by Alexander Brandon this time, but Michael McCann's fine compositions have no trouble what-so-ever in fitting in the setting.
A whole lot of minor flaws can be pointed out from Deus Ex: Human Revolution but they hardly affect how good the game is. And what a great game it is! Easily one of the best I have ever played. A very rewarding experience with awesome gameplay and story, good characters and room to choose how to approach your tasks. In fact, I have huge trouble resisting the urge to start a new playthrough right now to try all the things I didn't get to use on my first, 50 hours (+8 for The Missing Link) lasting playthrough.
