If you enjoy PC games, especially action RPGs like Diablo, but you've never once played Nethack, you probably should. No, seriously -- go, right now, download it, and check it out. Sure, it's hard, not very accessible (there are no graphics, only ASCII symbols to represent the player, items, and monsters), and enormously complicated. But it's also essentially the root of the "roguelike" genre (named after a game called Rogue), featuring random dungeons with dozens of levels, exciting turn-based combat, and plenty of unpredictable magic.

Desktop Dungeons is a game that continues in that tradition, though with one important twist: While Nethack, Rogue, and all of the other roguelikes take place over huge dungeons with multiple levels and lots of complexity, Desktop Dungeons champions simplicity. It takes place on basically one screen, in one grid, and that dungeon will cause you to level up from start to finish in just about ten minutes. It's the roguelike genre, boiled down into its most essential ingredients.

And it's glorious.
