Just finished a run of Sunless Skies. It's a trading and resource management game with horror elements (it's set in a Victorian England with angry otherworldly entities) and the writing is just superb. It starts off pretty tough - you have to explore the map blindly, so it's pretty easy to run out of fuel or supplies trying to find a port - but it quickly settles into a rhythm of "slightly challenging." I'll probably go back to it for other endings, but will probably work on my backlog first.
