YAY,!!! Finally got my copy of the game. I spend about 15 hours in game so far an am still in the middle of Detroit (I am a really slow player, have to look at everything in detail).
Got to say, so far I LOVE this game. It is exactly what I imagined it would be.
- Not far into the story yet so I can't say much but I have high hopes (the fact that the artbook has a picture that says "Bob Page's office" made me jump from anticipation

)
- Dialogues are superb, I like the system they have and the persuasion system with the aug is pretty cool. Only thing I don't like is that if you take some time to read all the options NPCs start nagging you, they should just have paused the situation IMO. Adams voice is very cool and reminds me of JC sometimes. Ambient conversations between NPCs are great and I like that people get phone calls and start texting from time to time (you shouldn't stay near one too long though).
- Didn't do much gunplay but the system seems very fluent (cover - peek out - iron sights - shoot). It's on par with ME2 (which is a compliment in my book) as far as I can tell
- stealth system is great, the combination of cover, first person and all the different paths for which often you need augs is really cool and almost like the old DX.
- I love the art style: Menues are slick and fit into the game, the black/gold color scheme is distinct and fitting,
- the environments are rich and detailed, almost to a point where you wonder how messy everyone seems to be (I mean, even the benches in sterilized labs are cluttered). What I love about it is that it is believable. Most games don't care about the fact an apartment needs separated living/sleeping and bathroom areas as well as a kitchen or that a decon area needs an eye shower. If you walk through the game you really feel like people live and work there which you don't see that often in video games.
- The hacking game is still fun at the moment although I think it has the potential to become annoying
- I don't know why people (in reviews) complain about the graphics so much. I think it looks great, sure, some texture are not top notch and animations could be improved but all in all I think, given the scale of some areas and all the other stuff that is going on, it looks great. Besides, the art style compensates easily
All in all, so far I am having a blast and if it keeps going that way, I found my game of the year 2011 (sorry Witcher 2, you will remain a close second)
