I absolutely love playing stealth in games that let me take that option. My preferred route in the Dishonored series is low chaos/ghost because of how challenging it can be, but I always reload saves to get though them because I like to experiment to see what works (and what doesn't), and also because I honestly just suck at getting things to go the way I want them to sometimes.
However, even though low chaos is apparently canon, I would like to point out that a stealth high chaos run where you murder every last guard/thug/weeper from the shadows can be sublime. Shadow Kill helps immensely here because when they dissolve into ash there are no bodies to hide (though half of the fun for me is finding out-of-the-way hiding places for everyone I've choked out and/or murdered).
And while it doesn't have nearly as much replayability because it ditches the chaos system entirely, Death Of The Outsider is loads of fun simply because you can literally do whatever you want, without having to worry so much about the consequences.
I'm also of those weird people who really likes the second game, too... maybe even more than the original, though they're both basically equal to me. Really don't understand the hate that one gets from some fans.
You get the same types of choices that you get in the first two games, but it's really streamlined. And you can absolutely murder/spare people as you see fit because it doesn't really affect the outcome. There is an achievement for clearing a single level without killing anyone, but not one for the whole game.
I didn't even realize there wasn't a chaos system until I finished the first level. I still played my usual way on that first playthrough, though (ghost/clean hands). On the second run I murdered everyone. Third run was the Original Game+ (where you get to use some of Corvo's and Emily's powers instead of your own)... that one was actually the hardest because Billie's powers are honestly better, at least in this one.
The only thing I've never really done in these games is go with the combat-- I'm purely stealth. I know the combat is amazing and completely open-ended, but I honestly suck at it.
