Oxygen Not Included

Oxygen Not Included is one of the best colony survival games on Steam, full stop. The pressure never lets up because every system, oxygen, heat, food, plumbing, stress, connects to every other system in ways that keep producing new disasters well into a hundred-hour run. It missed the main list because the interface friction on Deck is real. This was designed for a mouse, the information density requires zooming and scrolling that becomes laborious on handheld, and battery draw climbs during complex colony states. For a patient player prepared to sit with the interface learning curve, it is still worth the trouble.
