Pokémon Mystery Dungeon: Blue Rescue Team and Red Rescue Team

Pokémon Mystery Dungeon Red Rescue Team is for the Game Boy Advance, whereas Pokémon Mystery Dungeon Blue Rescue Team is for the Nintendo DS.

Gameplay
The game starts when the player is transformed into a Pokémon, which could be any of 16 Pokémon, chosen by taking a personality quiz. The partner can be one of ten Pokémon, which are one of the starter Pokémon from the 1st, 2nd and 3rd generation games. The mechanics of the game are that you lead a team of up to four Pokémon through a series of randomly generated dungeons in order to complete objectives, such as finding a particular item or rescuing another Pokémon. Successfully completed missions can advance the plot, and the player will be rewarded with Rescue Points and money or items. During these missions, when you defeat a wild Pokémon there is a chance that they might join your team if you have the requisite Friend Area, bought from Wigglytuff in Pokémon Square. You can recruit wild Pokémon in a dungeon until you either have four Pokémon on your current team, or the combined size of your team is too large.

The game itself focuses on traversing various dungeons in a simple turn-based fashion. Typically the goal for each is to simply clear the dungeon. Occasionally players will receive mail requesting they retrieve a lost Pokémon, deliver an item to a Pokémon in a dungeon, or escort an allied Pokémon, who temporarily joins the party, to another Pokémon in the dungeon. While missions are generally not required, they reward players with useful items and money.

All Pokémon from Generations I, II and III are available in this game; all may be battled and befriended as the player ventures across the land and into various dungeons.
