I bought this game thinking it was a cute, cozy cartoon colony sim from Klei. Instead, it systematically turned me into a mentally unhinged industrial dictator. First 10 hours: "Why are my dup peeing directly into the drinking water reservoir? Why is everyone suffocating in their own vomit?" 50 hours: Forced to open high school and college textbooks to re-learn the Laws of Thermodynamics, specific heat capacity, and fluid dynamics. 100 hours: Constructing SPOMs and Petroleum Boilers. Trapping Dupes in sealed chambers to run on manual hamster wheels 16 hours a day while feeding them mush bars and grilled worms. Realizing I have violated every single article of the Geneva Conventions. 200 hours: Experiencing clinical depression while attempting to complete the unholy trinity of Carnivore + Locavore + Super Sustainable before Cycle 100 without smashing my keyboard into pieces. 300 hours: Taming magma volcanoes, automating interplanetary rocket logistics, and genetically mutating crops with ionizing radiation. 400+ hours: I am now fully qualified for a Master’s Degree in Chemical & Aerospace Engineering, yet no university will give me a diploma. Summary: Art Style: 10/10 (Deceptively adorable trap) Gameplay Depth: 10/10 Psychological Damage: Permanent paranoia regarding ambient room temperature, gas pressure, and pipe insulation. 10/10. Best game ever. Do not touch this if you value your sanity, sleep schedule, or last shred of humanity.
Oxygen Not Included is one of those games that looks fairly simple at first, then suddenly you realise you’ve spent three hours redesigning a plumbing system because someone peed in the clean water supply. The amount of depth here is ridiculous. You start out worrying about food and oxygen, but before long you’re dealing with heat management, gas pressure, power grids, automation, germs, liquid loops and increasingly elaborate systems designed to stop your colony from killing itself. What I really like is that failure rarely feels completely random. Normally something goes wrong because of a decision you made 20 cycles ago that has finally come back to haunt you. There’s definitely a learning curve, and the game isn't particularly forgiving when you're starting out. You’ll probably restart multiple colonies as you realise everything you did in the previous one was horribly inefficient. But learning how everything interacts is a huge part of the fun. It’s basically an engineering problem disguised as a cute colony simulator, and if you enjoy building systems, optimising things and solving problems, it’s dangerously addictive.
Don't let the cute art style and the daft little dupes fool you. This isn't a chill builder, it's a thermodynamics PhD wearing a colony sim as a disguise. The title's a bit of a joke really, oxygen is the least of your worries once you're knee deep in heat management, gas distribution and a pipe network that's turned into spaghetti. What Klei have nailed is consistency. Gases, liquids, heat, power and automation all run on rules that stay the same no matter how chaotic the colony gets, so when something breaks it's always your fault, never the game cheating you. That's what makes solving it so satisfying. The first time a Self-Powered Oxygen Machine stabilises your whole base you feel like an actual engineer. It's deep. Properly deep. You're juggling temperature, oxygen, hunger, stress and comfort all at once, and every fix spawns three new problems. The flip side is the learning curve. The in-game teaching is thin, so expect to lose a few colonies before it clicks, and some folk bounce off it for that exact reason. Verdict: If you like colony builders with real systems mastery rather than hand-holding, this is one of the best around. Sitting at 97/100 across 135,000+ Steam reviews for good reason. 9/10, would suffocate my dupes again.
A cute, relaxing cartoon that secretly requires a Master's degree in thermodynamics. Oxygen Not Included is arguably the greatest Trojan Horse in modern gaming. On the surface, it looks like a delightful, casual colony sim where adorable little animated clones run around a colorful asteroid. It lulls you into a false sense of security with its charming, bubbly aesthetic and quirky animations. But do not be fooled for a second—beneath that cute exterior lies one of the most intricate, punishing, and deeply complex survival management games ever created. You think you're signing up for a chill time, and suddenly you are desperately trying to calculate fluid dynamics just to stop your base from filling with toxic gas. The way the gameplay scales is both terrifying and brilliantly addictive. Your first hour is wonderfully simple: dig a hole, build an outhouse, and find some algae to breathe. Easy, right? Cut to ten hours later, and your entire colony is collapsing because your clones accidentally peed in the fresh water supply, the carbon dioxide has pooled in the sleeping quarters, and your makeshift cooling system just boiled your only farmable food. The game throws layer upon layer of scientific mechanics at you—from plumbing and power grids to disease control and temperature management. It is the ultimate "time sink" game; you will blink, realize it's 3:00 AM, and you are still staring at your screen trying to perfectly route a single ventilation pipe. Despite how incredibly fast things can spiral out of control, it is a phenomenally fun and rewarding experience. The genius of the game is that every catastrophic failure is entirely your fault, but it’s also a learning opportunity that makes you want to immediately start a new colony and do it better. If you love games that let you tinker, optimize, and completely lose track of reality for hours on end, this is an absolute masterpiece. Just be prepared to spend an embarrassing amount of time Googling how real-world plumbing works. 10/10 — Everything is fine until the air turns yellow.
