Impressions: Oxygen Not Included

Oxygen Not Included (ONI) is a base-building and resource management game currently in Early Access, in the vein Dwarf Fortress and RimWorld. At least, that is what people tell me, as I have not played either one of those. What I have played is Craft the World (pt1, pt2), and ONI is basically that, minus the dwarves and goblins.

ONI_Base1

My first base. Doomed to failure.

The premise of ONI is actually kind of compelling. After picking three Duplicants from a roster of randomly generated ones, they appear in the middle of an asteroid. The ostensible goal is to survive as long as possible using what resources you have available. Instead of controlling them directly, you the player can generate and prioritize tasks like digging out certain squares, constructing machines, etc, and your Duplicants will work to make that happen. Contrary to the title, some basic oxygen is included in the form of oxygen-generating rocks, but it is not nearly enough to last long-term.

Indeed, oxygen-management is indicative of what you will be working on over the arc of the entire game. In the beginning, you will create machines that convert algae (mined from special squares) into oxygen to supply your base. However, your Duplicants exhale CO2, and that will gradually accumulate in the lower reaches of your base (science!). So, eventually, you are going to need to either research technology to convert that CO2 into some other form, or at least pipe it elsewhere. Meanwhile, you also have to grow food, find water, and research some method of disposing of all the poop (or polluted dirt, if you prefer) your Duplicants generate. Have I mentioned there are germs and stress to worry about too? And the fact that you are in the middle of an asteroid, so the whole “pump the CO2 elsewhere” is really just delaying the problem for another day?

Gas management is much better in my current base.

As of right now, I do not believe there is a story or “campaign mode” for ONI, and I do not know if there is any planned either. The goal is to survive as long as possible, and there are some very optimized base configurations out there to ensure that is the case. However… I’m not sure that is enough for me, game-wise. Klei’s other popular game, Don’t Starve, also features an implicit goal of surviving as long as possible against escalating threats. The end-state of death there though, usually comes from violence or mistakes rather than slowly running out of finite resources. I felt much more agency in Don’t Starve, in other words, even if the outcome was very similar.

What I will say is that Oxygen Not Included grabbed my attention very early with a compelling premise, and makes me wish there were more Terraria/Starbound/etc survival games out there that I haven’t already played . Hmm… maybe it’s time for RimWorld then…
