Gameplay
Pokémon Mystery Dungeon is an adaptation of the  games. Like the core series Pokémon games, it has two gameplay modes; unlike the core series games, battle mode and dungeon mode are not distinct. It is a turn-based game, with each step, attack, or item use being counted as a single turn.

The size of a party is limited to four in Pokémon Mystery Dungeon (three in Pokémon Super Mystery Dungeon), compared to six in the core series games. Furthermore, players are only able to directly control one Pokémon: their own character (or, later in the game, any other befriended Pokémon). The player's teammates are essentially autonomous, with player control being limited to general strategy such as avoiding Pokémon battles or not moving and staying in one place. The type of AI used by team members can be changed.

Most of the gameplay takes place within Mystery Dungeons, with many floors and hostile Pokémon. Due to the many dangers, exploration teams prepare for the challenges by using the many services offered at Pokémon settlements such as Pokémon Square and Treasure Town.

The games also feature storylines common in the aspects of the player having been transformed into a Pokémon and lost all memory of being a human, and an emotional separation from the befriended partner at the end of the main plot before the credits.
