Three weeks into early access, Slay the Spire 2 has reportedly out-earned two of the biggest indie hits in recent memory. According to analytics firm Alinea Analytics, the game sold an estimated 4.6 million copies on Steam in its first two weeks, generating over $92 million in revenue. You can check out the Steam community page to see just how active the player base still is.
For context, Alinea analyst Rhys Elliott notes that $92 million exceeds the entire lifetime Steam earnings of both Hades 2 and Hollow Knight: Silksong, each estimated at around $83 million. That gap is even more striking when you remember that Silksong crashed Steam servers, Xbox, PlayStation, and Switch simultaneously when it launched, such was the demand. Slay the Spire 2 quietly rolled into early access on March 5 and just... kept selling.
danger
These figures are Alinea Analytics estimates, not official numbers from Mega Crit. The only confirmed sales figure is 3 million copies after the first week on sale.
What the numbers actually tell us
The gap between the confirmed figure (3 million after week one) and Alinea's estimate (4.6 million after two weeks) implies roughly 1.6 million additional sales in the second week alone. That's a steep but plausible trajectory for a game that has held fourth place on Steam's Most Played list for most of March, with a daily peak of over 400,000 concurrent players.
As of the time of writing, Slay the Spire 2 sits sixth on Steam's top sellers chart. That's down from third the previous week, but still well inside the top ten for a game that launched over three weeks ago. Most titles fall off those charts within days.
Ten people built this
Here's the thing: Mega Crit, the studio behind Slay the Spire 2, was founded by just two people, Casey Yano and Anthony Giovannetti. The team has grown to around 10 people plus a few contributors. Silksong's Team Cherry has a core of three founders. Supergiant Games made Hades 2 with roughly 25 people.
All three games also took serious time. Silksong has been in development for approximately seven years. Slay the Spire 2 took around five years. Hades 2 clocked in at about four and a half years. None of these were rushed products, and the results reflect that.
The comparison makes a quiet but pointed argument about how games get made. Bloated budgets and hundreds of developers don't guarantee better outcomes. Sometimes a small, focused team with enough time produces something that outperforms the industry's biggest productions.
Deck building in early access
The ceiling is still far off
What makes these numbers even more notable is the context: Slay the Spire 2 is currently only available on PC via Steam early access. No console ports yet. No version 1.0 launch. The full release will almost certainly bring another significant sales surge, and additional platforms will open up entirely new audiences.
The official Mega Crit release announcement confirmed early access as the starting point, with the full game still to come. That means everything reported here represents a fraction of the game's eventual commercial footprint.
On the board game side, the Slay the Spire 2 Kickstarter campaign for the Downfall expansion, which lets players take control of iconic bosses like Slime Boss, Hexaghost, and Guardian, has already raised close to $2.6 million against a goal of roughly $50,000, with two weeks still remaining.
The momentum across both digital and physical products suggests this isn't a flash-in-the-pan launch. For a game still in early access, still on a single platform, the trajectory points well beyond what the current numbers already show. Keep an eye on the 1.0 release date announcement, because that will be the next major inflection point for sales figures. Make sure to check out more:
