Honestly? Great game. I went into this expecting it to be a dated title with some clunky mechanics that have shown their age after 10 years, but, surprisingly, I had a blast. The story is very predictable, the game is relatively short, and there are some other flaws -- but the gameplay and combat are too fun. It's just so satisfying to stop time and blink across the map taking down your enemies in stealth: you just feel like a ninja/assassin god. The gameplay loop never really got tiring to me, and there are plenty of different ways to approach each level which I would imagine makes replayability very favorable. I also really appreciated that the non-lethal options were always compelling, satisfying, and made sense within the greater, steampunk theme of the Dunwall world that is here. Overall, I definitely recommend this one -- it's not one of the best games I've played, but it's definitely going to be up there with some of my favorite stealth games ever.
What stands out to me the most about Dishonored is how Arkane Studios managed to create an incredible story and world that is alive and complex and then create a masterful stealth game that is jampacked with innovation that the genre has never seen and finally create a challenging gameplay system that slowly ramps up over the course of the game and never makes the player overpowered.
