About the game
This expansion for RimWorld introduces belief systems that shape a colony's culture and daily life. Players can lead communities built around very different worldviews — pirate-like nudist cannibals, blind mole-like people living underground, charity-minded ranchers, or transhumanists fixated on machines, among others. Ludeon Studios both developed and published the add-on in 2021, and the title sits in the indie, simulation, and strategy genres.

Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.

Global activates everywhere. Regional keys (Europe, North America, RU-CIS) only work on accounts from that region — use the Region filter to match your account.
What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
What's the difference between editions?
Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
