I've never played Dishonored but what is the game like?
Dishonored is pretty awesome. You play the Royal Protector in a fictitious kingdom called Dunwall which is like a steampunk version of Victorian London, I guess? Anyway, you've been framed for the murder of the Empress and you have to escape and take down the conspiracy that has taken over the throne.
Not the most original story, but the world-building is incredibly extensive, there's tons of ways to play the whole thing with many side missions that have an impact on that main mission down the line, different possible powers that you can acquire and tons of real consequences to either killing everyone or playing completely non-lethally or something in the middle. It also adds two DLCs which offer an interesting insight into one of the antagonists of the first part and they flesh out the world even further with some great tie-ins to the main game.
Definitely one of my favourite games of all time, I can strongly recommend you the game.
