103,243 concurrent players. 59,693 reviews at 93% positive. Three million copies sold in the first week. For most indie studios, that’s a career-defining launch. For Mega Crit, it’s a Tuesday afternoon in May — two months after Early Access began.

Slay the Spire 2 sits at #9 on Steam’s Top Sellers chart with no microtransactions, no live-service battle pass, and no cinematic marketing campaign. Just cards, relics, and the genre it helped create.

The Game That Built a Genre

The original Slay the Spire didn’t just popularize roguelike deckbuilders — it more or less defined the commercial category when it hit Steam in 2017. Monster Train, Inscryption, and Balatro all trace their DNA back to Mega Crit’s first effort. The original sits at “Overwhelmingly Positive” with over 200,000 reviews and a rating north of 97%.

Seven years later, the sequel arrived carrying the weight of a franchise that birthed an entire genre. By every commercial measure, it’s delivering.

The March 5 launch peaked at 430,456 concurrent players, according to SteamDB data reported by Polygon — enough to crash Steam for roughly half an hour. That peak more than tripled the previous roguelike concurrent record of 115,428 set by Mewgenics just weeks earlier. Within a week, Mega Crit confirmed three million units sold and over 25 million runs attempted. By mid-April, that run count had surged to 145 million.

What’s Working

The Early Access build ships with five playable characters, three acts, and ten Ascension difficulty levels. Player reviews consistently highlight three things: the strategic depth, the new multiplayer component, and the art direction.

“Fun to play, makes you think through strategies,” wrote one player with 22.6 hours logged. “Multiplayer is also really fun. Also love the drawings for the epochs — some should be kept in.”

That multiplayer component marks new territory for the series, and early returns are positive. Designer Yano told PC Gamer that three experimental modes are in the works — competitive, shortened runs, and a social-focused multiplayer option — though none have a firm release date.

The 4% Gap

Here’s where the picture gets nuanced. Ninety-three percent positive earns Steam’s “Very Positive” badge — a strong rating by any normal standard. The original Slay the Spire holds “Overwhelmingly Positive” status, typically reserved for games sitting at 95% or higher across massive review volumes.

That 4% gap isn’t a crisis. It’s nearly 60,000 reviews deep. But it reveals the specific burden of following a game people describe as flawless. Players aren’t measuring Slay the Spire 2 against other Early Access launches. They’re measuring it against one of the highest-rated games in Steam history.

Some of that 7% negative feedback is standard Early Access friction — balance issues, bugs, placeholder assets that Mega Crit has publicly acknowledged replacing. Some of it is the impossible weight of living up to a predecessor that defined perfection for an entire genre.

The Long Game

Mega Crit isn’t coasting on launch momentum. The April developer update laid out a substantial roadmap: a new character described as “mechanically complex” compared to the original cast, alternate versions of Acts 2 and 3, Steam Workshop support, a bestiary system, experimental game modes, and eventual console and mobile ports. The studio has also committed to ongoing balance patches, multiplayer quality-of-life fixes, and an official Twitch plugin.

Notably absent from the roadmap: dates. Mega Crit has been explicit about not committing to specific timelines for major content, preferring to ship when it’s ready. The original Slay the Spire spent over a year in Early Access before reaching 1.0. The sequel appears to be on a similar trajectory.

The numbers confirm Slay the Spire 2 is already a commercial hit. The real question is whether Mega Crit can close that 4% gap between “Very Positive” and “Overwhelmingly Positive” before the full release. The original built its legacy through patient iteration during its own Early Access run. The sequel has the player base, the revenue, and the runway to do exactly the same thing.

Whether the community’s patience holds through another year of balance patches and work-in-progress art is the only variable that matters now.
