I know you can pay as little as $1 for Humble Bundle’s latest Digital Tabletop Bundle 2, but I encourage you to get the real deal by paying $10 or more to unlock a Steam key of Slay the Spire. I’ve been playing it for a couple months now and it hasn’t lost its luster as the single best deckbuilding roguelike dungeon crawler I’ve experienced.
Since this is a “bundle” I should point out that you’ll also be getting a ton of other great games. At the $1+ tier you get Gremlins, Inc. Reigns and Reigns: Her Magesty. Beat the average (about $7 will do it) and also get Terraforming Mars, Armello, and For the King. And as I already prodded you about, $10 or more will add Slay the Spire to your kit.
