Dishonored
The first Dishonored is a contender for my favourite game of all time. The atmosphere, world, gameplay, and graphics all feed together to make a great narrative. All the games elements feel cohesive and well thought out. You can take a combat focus, a stealth focus or somewhere between and this will affect the story. Depending on how many people you kill the city of Dunwall will fall into greater troubles.
The powers can be both useful in stealth or combat with a slight leaning towards combat abilities which means some are a little useless in a complete stealth playthrough. I don't think this is n issue though just something to be aware of when playing.
The two story DLCs are also well worth playing for this one. They expand the story of Daud one of the characters you meet in the story and are just as well made as the base game. In total they have six levels which is about two thirds extra added on to the base game.
