Slay the Spire 2 developer Mega Crit is "totally blown away" by the immediate and colossal response to its long-awaited sequel, but it's exactly what the team deserves. If there's a 'second coming' for roguelike deckbuilders, StS 2 is it. The original is foundational to the genre, often imitated but never surpassed, and it's still elevated as one of the best examples of the form eight years on from its early access launch. Seeing Slay the Spire 2 break the half-million concurrent player count on Steam is another massive win for indie games in 2026 after the success of Mewgenics, and it's just the start.
