I just finished playing Dishonored. Good game! It was my first stealth FPS, so I had adjustment issues after gorging on Halo installments for so long.
Dishonored has high art direction value, taking a lot of aesthetics from Industrial age British fashion. That, and the dystopian decay plot point lends itself well to the alternative technology seen in the combustible whale oil. I was keen on this ever since looking into steampunk and alt-tech when I started Pale Blue Scratch. Dishonored even uses the vintage “natural philosopher” term for scientists.
See the gameplay below. You can also check out the three different types of endings here, depending on how much “chaos” you create. More killing = more chaos, and a less-happy ending.
