Dishonored looks like half-life to me.(oh spoilers inside)

Arkane Studios worked on a Half-Life game (that was cancelled )

Both this and Half-Life 2 had the same art director.

Blame Viktor Antonov

Viktor Antonov is the artistic talent behind Half Life 2. He's also the artistic talent behind Dishonored.

I personally thought there were too many similarities in both games. Certainly in terms of those metal walls that conveniently block off access to other parts of the city.

And yes, I found the game way too easy. Now if only they took out Blink.....

I find it much more similar to Bioshock. The atmosphere, the care for the details, the supernatural powers, even the graphic style is really alike. Anyway, I think Dishonored is quite a good game, far above the average (which is pretty low this days). They've managed to mix Deus Ex: HR gamestyle with Bioshock and the outcome coulnd't look better.

PS: Anyone who doesn't try to play the stealthy way won't never enjoy the full experience this games offers. There are so many ways to play it that simply killing guards is too damm boring.

tl;dr

i have seen some vids i think its looks good so does it mather?

As soon as I first saw a trailer of the game I thought, Oh wow there's a new HALF LIFE!!! Turns out that there's the same art director
