A quick summary: a space colony survival strategy, with gameplay a bit reminiscent of Dwarf Fortress, a selectable-logic AI "dungeon master" that generates events and manages difficulty progression for the player's colony, and a space + wild west setting that's a bit reminiscent of Firefly.
Anybody have any experience or impressions of it so far?
Currently in early-access alpha. Considering grabbing it for myself.
