Pokémon Mystery Dungeon is a spin-off video game from the main Pokémon series. The games feature the fictional creatures called Pokémon who have the ability to speak human language navigating through a randomly generated dungeon using turn-based moves, common to Mystery Dungeon games. As of March 2020, there have been eleven games across five platforms, as well as several manga adaptations and animated specials. These games are based in dungeons (“mystery dungeons”) where a floor map is randomly generated. In the dungeons, players fight other Pokémon while obtaining items and finding stairs to the next floor, exiting the dungeon after a fixed number of floors. Across all installments, the series has sold over 17.26 million copies.
