I haven't played a lot of Single-Player games- so far I've only completed Mass Effect 1, and Dishonored. but even if i were to factor in all the Multiplayer games I play, I would say Dishonored is probably my favourite game. Ive played it through once, and I still feel (
read light novels online) that there's loads of ways I could play this game; it has great replayability and Open-World elements, a great story, and the player’s choices really impact how the game turns out. My first run was me trying to not be detected and not kill anyone, and it took me loads of saves, 40 hours, and I still enjoyed every second of it.
