Hey everyone. RimWorld turned ten years old on November 4, 2023, and it's just in time for the 2023 Steam Awards. You can nominate RimWorld under the "Labor of Love" category!

It's been ten years of content from the Kickstarter, alpha, beta, and Steam greenlight days, plus game updates, lore, fanart, videos, streams, memes, Royalty, Ideology, Biotech, Steam Deck, console release, and much more I didn't cover. We're really proud of RimWorld and our community. Here's to more RimWorld!

The Steam Autumn Sale just started as well, and we're running discounts on ... Read more

Hello, it’s Tia! I’m here to share a small update just before the holidays. ❄️️

Today’s update comes with a looong list of fixes. Loads of these were made with the help of our testers - a big ol’ hug and huge thank you for helping us squash those bugs! Now children are less likely to run headfirst into danger and bestowers will get the heck outta there if they’re breathing in poisonous gas. We also added a few tools to help out our modders and community translators do their thing. The changelog is below to read over.

If you want to keep playing on the previous version of 1.4, you can use the Steam beta branch "version-1.4.3563". To do this, r-click RimWorld in the Steam library, go to properties, open the betas tab, and select the version from the dropdown.

Hi everyone. Valve has recently released their new recommended currency conversions for Steam games and many game studios are beginning to implement these.

We are planning to follow Valve’s recommendations and update some of our non-USD price conversions. (Note that none of our base USD prices will change - this is only about updating currency conversion rates.)

In most cases our prices will remain lower than what Valve recommends. The major currencies will generally see increases of 2-10% - this includes Euros, Chinese yuan, British pounds, Canadian dollars, Australian dollars,... Read more
