"Mystery Dungeon features a distinct gaming style: it's all about randomly generated dungeons in a turn-based, real-time RPG hybrid design. The whole idea of Mystery Dungeon revolves around working your way through a series of multi-level dungeons, with each floor being generated on the fly when you get there. What this means is, potentially, you'll never see the same floor layout twice if you decide to enter the same dungeon multiple times, but since the dungeons are incredibly basic, tiled and angled layouts it's not that huge of a deal. And many times the dungeon generator will create a level that requires no exploration at all – you'll often find yourself placed in a room where you're standing right next to the exit".
