Posting rules, in plain words
Self-promotion is judged case by case.
- Self Promotion: Guides are OK, Let's Plays are not: Content should contribute to discussion, linking a detailed stream explaining a mechanic is allowed, linking a playthrough is not. If the aim of your comment or post is to get views or subscribers, [please use our sister sub Rimworld Streams](https://www.reddit.com/r/RimworldStreams/). Links to YouTube videos and streams should serve a purpose.
Quoted from the community’s own published rules. Always re-read them before posting.

- — Humorous and ironic, often playing into the game's dark humor.
- — Specific to RimWorld mechanics and common player experiences.
- — Uses in-game terminology and references.
- — Often includes images or memes to enhance the comment.
- — Relatable to other players' experiences, especially regarding 'war crimes' or optimization.
- — Short, punchy, and often builds on previous comments in a thread.

How active is r/RimWorld?
We don't have a reliable posting-rate sample for r/RimWorld yet. Subscriber count alone is a poor guide to whether a community is active, so treat this one as unverified until the next sample lands.
When was r/RimWorld created?
r/RimWorld was founded in September 2013 and is a public — anyone can post community. Age matters: an older community with steady growth has survived Reddit's moderation churn; a young one with a spike may not.
