Make sure you like reading before you commit to this one. The atmosphere is opressing and dim and eldrich, and the characters that you meet are the same. I got very into planning optimal routes to build my funds to fuel my exploring of the underground.

Theres a lot to discover if you have the patience for it, but this is the kind of management and exploration sim that builds steam as it goes.

The setting is the big draw here, which is good because it's so well realized.
