I hate to be mister poopy pants, but I've got to say I had the complete opposite experience with the first hour of Dishonored.

* The art style instantly rubbed me the wrong way. Very generic and unimaginative. Some elements were pulled straight out of Fable, others from Fallout 3, etc. And everything is brown. I guess weI did really like the "oil painted" quality of the textures and color blending though.

* The "Hide and seek" segment illustrated the fundamental flaw with employing a First Person Perspective in this game: "Hiding" basically means crouching behind cover and staring at a flat texture for 20 or 30 seconds. It was well implemented from a narrative point of view, but the raw mechanical gameplay is just dull.

* The game is full of outdated issues. The fact that every character in the game is voice acted EXCEPT for the player character feels very out of place and jarring. When you pick up a throwable object it just floats suspended in air in front of you, rather than being held in your hand. For every element that tries to pull you into the world, there is another that pulls you right back out.

* I couldn't believe how often control was taken away from me in the first hour of the game. I feel like I spent well over half my time staring at blocky looking characters as they have one-sided conversations with my mute protagonist. This felt particularly clunky because the dialog often included expository information for the sake of the player: information that my character should already know given his position in the story.

Overall, I really found it to be a very dull, clumsy experience.
I'm glad others are enjoying it, but it's just not for me. :-/
