Pokémon Ranger for the Nintendo DS is an action-adventure role-playing game where players take on the role of a Pokémon Ranger in the Fiore region. Unlike traditional Pokémon games, players use a stylus to circle and befriend Pokémon rather than capture them in balls, with the goal of solving environmental puzzles and aiding various Pokémon in distress. The game features real-time Pokémon capturing using the DS's touchscreen and focuses on completing missions, aiding Pokémon, and thwarting the nefarious plans of the Go-Rock Squad. It offers a unique twist on the Pokémon formula, focusing on protection and partnership over battle.
