Pokémon Ruby and Sapphire take place in Hoenn, a fictional region based on the island of Kyūshū in Japan.This region, one of many in the Pokémon video games, contains nine cities and six towns along with different geographical locations and Routes connecting locations to one another. Some areas are only accessible once the player learns a special ability or gains a special item; for instance, the player must acquire the HM Surf, which allows the character to ride certain Pokémon on water, in order to reach Mossdeep City.

The protagonist of Pokémon Ruby and Sapphire is a child who has recently moved to Littleroot Town. At the beginning of the games, players may choose either Treecko, Torchic, or Mudkip as their starter Pokémon from Professor Birch. His child, the protagonist's rival, has also become a Pokémon Trainer and will battle the player at certain points in the game to test the player's Pokémon.

The basic goal of the game is to become the best trainer in all of Hoenn;this is done by raising Pokémon, defeating the eight Gym Leaders for Gym Badges, and eventually challenging the Elite Four and the Champion.Also throughout the game, the player will have to battle Team Magma or Team Aqua (depending on the version of the game being played), a criminal organization that abuses Pokémon.

New features

In this double battle, one of the player's Pokémon uses a move against an enemy Pokémon.

The most prominent change in the battle mechanics is the introduction of double battles, in which the opposing parties each use two Pokémon at same time. Consequently, certain Pokémon moves can affect multiple combatants at once.Also new to the games are innate abilities and natures; the former is shared by every Pokémon of a certain species, while the latter may vary among a particular species. Abilities grant their holders certain powers in battle, such as immunity against certain types of moves or strengthening a certain type of move. Natures, like innate abilities, affect the strength of Pokémon in battle; however, they do so by affecting the stats of the Pokémon rather than directly affecting the strength of the moves.Another stat introduced in Pokémon Ruby and Sapphire is Condition, which can be increased by using Pokéblocks, candies made from berries. Each Pokémon move also has a Condition, and it is a major factor in Pokémon Contests, mini-games in which trainers display their Pokémon by having the Pokémon perform moves.

Like Pokémon Gold, Silver, and Crystal, Ruby and Sapphire keep track of real-life time; this influences events like tides and berry plant growth. However, unlike their predecessors, Ruby and Sapphire do not differentiate between the phases of the day (Morning, Day, and Nite in Gold and Silver); thus, the appearance of Pokémon is not tied to a certain time of day. In addition, due to the changes in battle structure as well as new Pokémon statistics, Ruby and Sapphire cannot be linked with Pokémon games of previous generations.
