Each DLC Explained (What It Actually Adds)
Royalty (2020) — Space Feudalism
- Adds: the Empire faction, psycasts (magic-like psychic powers), royal titles and obligations, honor/royal favor mechanics, new weapons/armor
- What it's for: gives colonists a "class" progression — pawns can become psykers/royalty with real power
- Community verdict: solid, but the oldest — its content is now the baseline many players expect
Ideology (2021) — Culture & Beliefs
- Adds: custom belief systems (memes), rituals, festivals, social roles, leader/preacher roles
- The famous example: play as piratical nudist cannibals or blind underground mole-people — your ideology defines what's "normal"
- Community verdict: the most transformative — changes how you play every game (arguably the best value)
Biotech (2022) — Children & Genetic Engineering
- Adds: children (pregnancy/birth/raising), mechanoid control (build and command robots), xenogenes (genetic traits, custom races)
- Community verdict: the most content-dense — families, mechanitor builds, and gene-modded colonists change the mid/late game dramatically
Anomaly (2024) — Horror & Cults
- Adds: horror events (entities, anomalies), cult mechanics, void/monolith content, the game's creepiest events
- Community verdict: strong atmosphere and events; the most "story-generator" of the DLCs (great for players who love the chaos)
Odyssey (2025) — The Space Adventure
- Adds: the space expansion the community waited years for — shipbuilding/space travel, new frontier maps, new events and endgame content tied to leaving the planet
- Launch reception: widely called "the best DLC yet" by reviewers and community on release (July 2025), framed as the space adventure the game was always leading to
- Community verdict (2026): the top recommendation for veteran players — and the most exciting for people who want an actual "escape the planet" endgame
Ranked: Which DLC to Buy First
The community's consensus ranking (2025–2026, e.g., G2A's ranked list and Reddit's "explain the DLCs" threads):
- Biotech — most content, most transformative (children + mechanoids + genes)
- Ideology — changes every playthrough (culture systems)
- Odyssey — the newest big expansion, best for veterans/space content
- Royalty — solid baseline, but feels like the oldest
- Anomaly — great atmosphere; the most "optional" if you dislike horror
For beginners: start with Biotech (or none — the base game is complete). Buy the rest once you've burned through the base game's content.
None of the DLCs are required — RimWorld's base game is a complete experience. The DLCs are "more RimWorld," not missing features. If budget is a factor: Biotech first, then Ideology. Odyssey is the pick if you're a veteran who wants the space endgame.
