Slay the Spire 2 dev says an early idea was to actually reduce the card pool, but players hated it: ‘We need new stuff!’
Casey Yano, co-creator of Slay the Spire and co-founder of Mega Crit Games, discussed early design decisions for the sequel in an interview with Edge magazine. During development, the team considered reducing the card pool as a design direction, but player feedback on this concept was decisively negative. Test audiences rejected the idea, expressing a clear preference for new content rather than a streamlined approach. As one voice captured in the article: “We need new stuff!” This reaction reflects a broader design challenge facing the sequel: the original Slay the Spire “pretty much got it right first time,” making clear decisions about what to keep, change, or expand particularly complex. Rather than pursuing the card reduction concept, the development team ultimately moved in a direction that expands the game’s offerings. The insight illustrates how roguelike deckbuilders rely heavily on deck variety and replayability—core to player enjoyment—making additive design choices more appealing than subtractive ones for sequels in the genre.
