Best DLC Purchase Order
For most players, the best RimWorld DLC purchase order starts with Biotech for breadth, then Ideology for colony identity, then Royalty or Anomaly depending on whether you want power fantasy or horror pressure.
01Overview
RimWorld DLC is not just more content. Each expansion changes what kind of colony you are building. Biotech adds children, genes, xenotypes, mechanitors, and a huge amount of pawn-level variety. Ideology changes colony identity and moral rules. Royalty adds the Empire, titles, permits, and psycasts. Anomaly adds horror progression and containment-focused threats.
If you are brand new, play some base RimWorld first. Once you understand food, raids, research, medicine, and mood, DLC becomes much easier to judge.
02Why It Matters
The wrong first DLC can overwhelm a new player or add systems they do not actually want. Someone who wants more everyday colony variety will usually enjoy Biotech sooner than Anomaly. Someone who wants themed challenge colonies may value Ideology more than Royalty. Someone who wants supernatural combat tools may love Royalty, while a horror fan may put Anomaly higher.
Good purchase order is about playstyle fit, not release order.
03Practical Uses
Use this page as a decision guide. If you want the most broadly useful first expansion, pick Biotech. If you want colonies to feel culturally distinct, pick Ideology. If you like noble titles, psycasts, and Empire quests, pick Royalty. If you want a separate horror arc with strange entities and containment pressure, pick Anomaly.
Mod users should also consider compatibility. Many popular mods build heavily around Biotech genes, Ideology memes, and Royalty psycasts. Anomaly support is growing, but its content is more specialized by nature.

06Community Opinions
Community recommendations often put Biotech first because it adds the most broadly useful systems and feels integrated into normal RimWorld. Ideology is commonly recommended for players who want roleplay and colony variety, but some warn that it changes the feel of every run. Royalty is often described as fun but narrower, especially if you do not care about the Empire or psycasts. Anomaly is the most polarizing: loved by players who want horror pressure, skipped by players who prefer classic colony simulation.
The repeated community warning is also important: learn the base game before stacking every DLC and a large mod list.
07Common Mistakes
08Recommendations
My default recommendation is: base game first, then Biotech, then Ideology, then Royalty, then Anomaly. Change that order if your preferences are strong. Choose Ideology before Biotech if themed roleplay is the main appeal. Choose Royalty earlier if you want psycasts and Empire progression. Choose Anomaly earlier only if horror is the reason you are excited to play.
For budget-conscious players buying one DLC, Biotech is the safest broad recommendation. For players who already have hundreds of hours and want colonies to feel morally and culturally different, Ideology may be the more refreshing second purchase.
