I can hold my sense of disbelief in regards to the leaning. It’s very hard to pull off peeking around corners realistically to the point where I can only remember the Crysis games doing it well.
Thinking about the genre, or sub-genre, or sub-sub-genre, Where is all the coal? I’d say it counts as a post steampunk world if whale oil is an improvement over coal in the universe. I’ve noticed some smoke towers, so I assume it’s is about.
Regardless, AWESOME game. I’ve been playing the first time through doing everything how I want. The second time I intend to slaughter absolutely everything in my path as I haven’t seen too much combat this time. Then I’l go super stealth.
