Oxygen Not Included: Spaced Out! vs Rain World: which should you buy?

Oxygen Not Included: Spaced Out! is the better pick for players who want to build systems, while Rain World is better for players who want to explore a hostile world. Both are single-player games, but their moment-to-moment decisions feel completely different.

Oxygen Not Included: Spaced Out! expands a colony-management game with multiple planetoids and additional logistics. Rain World centers on a vulnerable slugcat navigating regions full of predators, shelter and scarce resources. Choose Spaced Out! if you enjoy planning oxygen, heat and supply chains. Choose Rain World if discovery and survival tension sound more exciting. Remember: Spaced Out! requires Oxygen Not Included.

Does Oxygen Not Included: Spaced Out! require the base game?

Klei Entertainment Oxygen Not Included: Spaced Out! requires Klei Entertainment Oxygen Not Included, so the expansion is not a standalone purchase. The base game supplies the core colony systems; Spaced Out! adds a broader planetoid and rocketry framework.

New players should start with the base game and learn how duplicants, oxygen, food and temperature fit together. Returning players who understand those systems get more from the expansion’s multi-world management. Check your library before buying an add-on, and match the expansion to the exact platform and edition you play.

Is Rain World or Rain World: Downpour better for a first purchase?

Videocult Rain World is the right first purchase for newcomers because Videocult Rain World: Downpour requires the base game. The original introduces the slugcat, ecosystem and survival rhythm before the expansion adds more campaigns.

Start with the base game if you want to learn how to navigate, hide and read creature behavior. Choose Downpour when you already own Rain World and want 5 additional playable slugcats with distinct stories. The expansion is a content upgrade, not a replacement for the original campaign.

Which colony sim is best: Oxygen Not Included, RimWorld or Dwarf Fortress?

Klei Entertainment Oxygen Not Included is best for engineering-focused survival, Ludeon Studios RimWorld is best for character-driven colony stories, and Bay 12 Games Dwarf Fortress is best for simulation depth. Each is a single-player management game, but the learning experience and priorities differ.

Oxygen Not Included pushes players to solve practical base problems such as oxygen and heat. RimWorld uses 3 storytellers to shape event pacing around a settlement. Dwarf Fortress builds a procedurally generated world and asks players to manage a fortress within it. Pick the one whose central challenge sounds fun, not simply the one with the longest feature list.

Are Black Friday 2026 game picks better on PC or console?

Platform fit matters more than genre labels: check each game’s store listing for supported hardware, controls and edition details before choosing. This guide focuses on the games’ core experiences, while exact platform availability and add-on compatibility depend on the version you plan to play.

Colony sims often involve frequent menus and detailed management, so confirm that the controls suit your setup. Rain World’s precise movement also rewards comfortable input. If you are shopping for a console, handheld or PC library, verify that the base game and any expansion match the same platform. A DLC purchase for the wrong version will not extend your game.

Buying Guide

Choose the core loop first

Pick colony management for planning and optimization, or Rain World for exploration and survival. Against the Storm suits players who want settlement strategy in repeated runs.

Check base-game requirements

Oxygen Not Included: Spaced Out! requires Oxygen Not Included. Rain World: Downpour requires Rain World. Buy the base game first if it is missing from your library.

Match the learning curve

RimWorld and Dwarf Fortress reward patience with complex systems. Rain World is demanding in a different way: learning creature behavior and navigation is part of the challenge.

Think about replay style

Choose a simulation that supports long-term colony goals, or a run-based game such as Against the Storm. Rain World’s expansions add more campaigns for players ready to return.

Verify platform and edition

Check the storefront listing for your platform, supported controls and compatible edition. Confirm that an add-on matches the base game already in your library.
