Dishonored 1 was more fun for screwing around but I love them both. It's worth doing a serious play through where you try to not kill people and work out the perfect route to places and then do a max carnage play through
I enjoyed doing a mixed play too, kill every soul you can find, but no one see anyone die from their perspective people just vanaish, you dispose or hide all the bodies. I had a lot of bodies hidden in the celings....
