5.3 million copies crushing “Crimson Desert”? Where does “Slay the Spire 2” win?

This time they made a rather radical trade-off in terms of product format: using what looks like an “old-school” card-based roguelike to go head‑to‑head against the marketing blitz of open-world blockbusters, and the March Steam sales chart immediately delivered the verdict.

Looking at the data, Slay the Spire 2 sold about 5.3 million copies in March, with revenue of around 108 million USD, taking the top spot as Steam’s best‑seller of the month. This scale is far beyond what you’d call a “well‑reviewed niche indie game” and is much closer to the revenue pace of a frontline AAA new release. Compared to the first game, which needed nearly two years of Early Access and two months after full release to hit about 1.5 million copies, the sequel has clearly done multi‑layered optimization in both design and marketing. It’s as if they re‑packaged the already mature “deckbuilding + tower climbing” system into a product bundle that’s easier for mainstream users to understand.

From a design perspective, card‑based roguelikes naturally have a “repeat purchase loop” advantage: the decision tree of a single run is rich enough, the combination space of card pool and relic pool is enormous, and every run feels like an auto‑generated new level. This kind of gameplay structure, which heavily reuses content assets, is far more cost‑efficient than an open world spanning hundreds of square kilometers. In the March window, it formed a sharp contrast with Crimson Desert, which pushes hard on visuals and scale. It’s like a character who invests all stat points into art and storytelling meeting one who pours them into systems design and replayability; the gap in user lifetime value between the two quickly shows up in the sales curves.

From a business logic standpoint, Crimson Desert is not exactly a failure either. According to analysis, it sold close to 2 million copies on Steam in March, with total revenue across all platforms surpassing 200 million USD. That’s an impressive return for any development team. However, its “mixed” reception at launch meant it couldn’t generate sustained positive buzz in the community. For open‑world narrative projects, early development is like piling up assets, and later you’re slowed by all kinds of technical debt. If the core gameplay loop hasn’t been fully polished in the end, players’ feedback will be brutally direct. In contrast, for system‑driven products like Slay the Spire 2, polishing the core combat loop is like grinding a highly focused mini‑update: once the feel is nailed down, users naturally want to contribute more “one more run” playtime and word of mouth.

From a technical perspective, these popular March releases actually occupy different risk levels. A linear single‑player continuation of a big IP like Resident Evil 9: Requiem sold about 1.2 million copies on Steam in March, generating 70 million USD in revenue. Total sales on the platform are now around 2.9 million copies, and across all platforms it broke 6 million in a little over two weeks. This is a highly efficient product from a mature pipeline, with technical solutions and asset production lines that are highly reusable. Meanwhile, Capcom’s upcoming Kunitsu‑Gami: Path of the Goddess, launching April 30 on Steam, XSX/S, PS5, and Nintendo Switch 2, is a typical example of “engine‑level” investment traded for wider “release footprint.” From an engineering standpoint, cross‑platform adaptation will be very demanding, but it’s also the most straightforward way to spread development costs across a larger market.

Back to the player’s perspective: if you’re struggling with which game to buy in the March window, my suggestion is simple. If you want high‑value replayability and are willing to chew on system depth, prioritize Slay the Spire 2; its design is literally built for “playing many runs.” If you care more about cinematic storytelling and big set‑pieces, consider Crimson Desert, but be prepared to accept its somewhat rough system details. As for Resident Evil 9: Requiem, a traditional single‑player blockbuster, you can treat it as a highly polished “linear experience package”: play it chapter by chapter after work, the experience is smooth but leaves limited room for replay. Behind these three games are essentially three completely different development philosophies: some pour resources into sheer content volume, some obsess over systemic coherence, and others rely on mature IPs to replicate a successful template. The March sales chart simply uses numbers to give us a very intuitive A/B test.
