Prior to its release, the game was often known as Pokémon Ranger: The Road to Diamond and Pearl (Japanese: ポケモンレンジャー ダイヤモンド・パールへの道).
The goal of the game is to travel all over the land of Fiore to capture all the 213 Pokémon that are available using the Nintendo DS touch screen and stylus.
Instead of capturing Pokémon in Poké Balls, players use a device called the Capture Styler to add Pokémon to their party.
