The peaceful, pleasant farm-life sim Stardew Valley (opens in new tab) was released on Steam in February 2016, and by April it had surpassed one million copies sold (opens in new tab)—a big benchmark of success for just about any game, and particularly for a niche indie release developed entirely by one guy. Four years later, the game is available on Mac and Linux, consoles, and mobile devices, and it's now moved past ten million.
Stardew Valley has sold over 10 million copies. It's strange & amazing to think back to when I was making this game in my bedroom w/ no clue if anyone would like it. Only 4 years ago! To everyone who has played this game, supported it, and made all of this possible: Thank you!!January 23, 2020
The sales aren't broken down by platform, which is unfortunate, because it'd be interesting to see how PC, console, and mobile numbers compare. Very casually, it appears that Steam still dominates handily: SteamSpy (opens in new tab) pegs its ownership numbers through the storefront as between five and ten million, so even at the low end that's half the total ownership.
One of the nicest things about Stardew Valley hitting this milestone has been the reaction from the community. Reddit isn't always the most uplifting place on the internet, but the messages in threads on r/pcgaming (opens in new tab), r/NintendoSwitch (opens in new tab), r/StardewValley (opens in new tab)(naturally), and others are honestly heartwarming.
And never forget: It all started with a Costco rig and a monitor balanced on a Wii box (opens in new tab).
