I think Dishonored Definitive Edition (first game , remastered) is a good option to begin .

After that , Dishonored 2 , and lately Dishonored : Death Of the Outsider . That's the order cronological to play . Enjoy :) .

Definitely start with the dishonored definitive edition (the first game). After u finish that, play the dlcs with daud because they're quite fun. Then move onto dishonored 2 then the death of the outsider. In my opinion dishonored 1 is better than dishonored 2
