- RimWorld is an emergent narrative engine with stronger combat/story spikes.

Choose Oxygen Not Included if…
- You like solving heat, gas, and liquid problems
- Base failure from physics sounds like a fair teacher
- You want less RPG drama and more systems plumbing
Choose RimWorld if…
- Colonist stories and mental breaks are the hook
- You want raids, relationships, and ideology-style depth
- Narrative emergence beats fluid dynamics
Avoid Oxygen Not Included if…
- You don't want to lose a base to a cascading heat or gas failure you didn't see coming
- You want a gentle learning curve — every ~30 hours a new system arrives and breaks your assumptions
- Reading wikis and doing rough math for a "fun" game sounds unappealing
Avoid RimWorld if…
- You want clear objectives rather than an AI storyteller improvising disasters at you
- Losing colonists to a raid you couldn't have prevented would ruin the game for you
- You're not willing to buy DLC to get the full intended experience
