Drop Duchy first caught my eye with a demo at a recent Steam Next Fest. With the full game now out on Steam, it turns out Drop Duchy is a deeper, more satisfying strategy game than I would have imagined, all built on the idea of stacking blocks. Drop Duchy’s deckbuilding twist on Tetris may sound strange, but it’s a delightfully original puzzle game. Not all is peaceful in your blocky kingdom, though, and the real strategy of Drop Duchy kicks in with military cards. Drop Duchy transforms Tetris into a challenging strategy game.
