It's the game of the year edition, and it only costed 14,50€ (I think that's a little more in dollars)
I have played the game for about 5 hours now, and I'm impressed! I know it's made by Bethesda, and even though I loved Skyrim too, this game just feels so... cool! In Skyrim, I got an epic experience, but the gameplay felt so boring (unless you sneaked all the time... The sneaking's fun, but way too easy in Skyrim)
In Dishonored, everything feels right! The characters, the story, the gameplay, the enemy AI, music, etc. I just LOVE that game!!!
