Where to play
RimWorld is on Steam. When the eventual Tavern store launches, you'll be able to buy it through Tavern with full transparency about the +$0.05 convenience markup — but the actual transaction will still happen on Steam, and the game lands in both your Tavern library and your Steam library.
