Similar to Oxygen Not Included?

I know it's not exactly a clone but same kind of game, if you like ONI you'll probably like this?

ONI relies way more on machine setups and it always has a collapsing feeling until you get established. RimWorld is more of a chill game where most of the difficulty comes in the form of random events, whether it be raids or a solar flare or volcanic winter. The events may come all at once if you're on Randy Random which make for a chaotic but extremely fun gameplay. Otherwise you have the more systematic Cassandra which has a basic schedule she keeps to when it comes to sending raids at least. Or Phoebe which is a bit of of a newbie trap where you'll gain a lot of wealth without staying ahead of the defense curve.

RW is similar to ONI in that;
- It is a colony base-builder sim
- You start with a small group of randomly generated pawns with unique traits and skills
- You build and do research to learn new tech that lets you build new stuff to deal with your problems.

They are different in that;
- RW has a lot more focus on combat, being raided by / trading with other factions (diplomacy), and defending against attacks.
- ONI has much more intricate and detailed simulation of things like gasses, heat, and disease/contamination.
- RW is a lot more "story-based", in that colonists can develop relationships (both good and bad), get married, be jealous, have kids (if you have Biotech DLC), etc.

I like both games and would recommend trying out RW to anyone who has the patients to appreciate ONI, but they are definitely two extremely different games when taking more than a basic look at them.

RW is more of a Mad Max soap opera generator sim, while ONI is more focused on the base-building and exploration elements.

ONI is an engineering sandbox. Rimworld is a war crimes simulator.

What I mean by "collapsing feeling" for ONI is that everything can cascade if not properly managed because of it being a limited resource game up until very late game, that being temperature control, heat, very limited resources, oxygen, water, carbon dioxide which are all very heavily interconnected in the limited space ONi gives you.

RimWorld is much more simplified where once you learn the core gameplay (though it takes quite a long time to master it) it's about optimization and learning to deal with the events you will inevitable be hit and the enemies that will come as you continue to progress. For example if you were playing on Peaceful in RimWorld you could live indefinitely just from learning mood, food and temperature management. On that difficulty there isn't a push continue progressing but as soon as you go to higher difficulties you have to deal with raids and you want to continue progressing your tech so that you can handle bigger and more well armed enemies. You want more control over your colony's destiny by getting bigger and better defenses with uranium slug turrets, autocannons, mini turrets, you want to enhance your colonists with marine armor, bionics, charge rifles and the lot to make sure your colonists have their best chance at surviving what the game throws at them. But on top of that there are events which may test your colonies fortitude outside of combat, solar flares which disable all electronics for 12 hours, nuclear winters which suddenly blanket the ground in snow and test your food supply, cold snaps which very easily kill all crops within a few hours, short circuits which end up causing fires in your colony, toxic fallout which will limit how long colonists can stay outside during the event before they get increased risk of cancer and dementia, psychic droners which can drive your colonists absolutely mad, testing your ability to keep mood high with extra luxuries for your colonists.

I have a habit of unintentionally calling my pawns in rimworld dupes.

ONI is hard to delve deeper into. The early game is intuitive but all of this advanced stuff, many of us won't get that far. They keep adding new stuff to later points in the game and the early game hasn't been updated in years. Now Rimworld, you can figure out whatever you want to do.

ONI is very similar in how you play the game, but the type of gameplay is different. ONI is more about the facility you build around your 'pawns', whereas Rimworld is about the pawns and managing them. I don't think in terms of content they are similar at all, but if you like management games in general you'll enjoy Rimworld and you'll find the UI very intuitive based on your ONI experience.

Gun to my head I'd say Rimworld is if the early game of ONI was extended to be the entire game. You have to build an infinite variety of bedrooms, toilets, and water tanks. But instead of someone vomiting in your water tank someone artillery strikes it.

Everyone else has it explained it quite well: in the general motions it plays similarly, but your actual thought processes and goals going in are pretty different. I also find Rimworld a bit more flexible for personal ideas/goals than Oxygen Not Included and appreciate it more for it.

Well written. This.^

In my first ever successful playthrough in a Desert biome I recruited a pirate after giving him a bunch of beatings and tearing off his nose as a result of his escape attempts, changed his nickname to "no-nose" and made him my colony's cook since he had burning passion for combat and cooking. Later on he lost a leg, an arm and got minor brain damage, fell in love, got married, ate some raw human flesh and puked all over his lover and their bedroom. Why am I telling you this? Because it is a fond synthetic memory created by emergent gameplay in Rimworld, a story generator.
ONI is a fun engineering game and at best the storytelling ends in you making a mistake in design which disrupts your supply chain or waste management. Duplicants are just another resource with some slight variation in types of breakdowns.
Depends what you enjoy about a game. If you like the engineering aspect maybe you could try getting into Factorio?

ONI wont let you turn your enemies into human leather hats and sell those hats to your friends.

But it will let you drown your colonists in their own urine.

You can also stress your dupes until they start vomiting or crying and recycle the water for colony use.
