Pokémon Ruby(JP) and Pokémon Sapphire(JP) are part of the third generation of Pokémon games (also known as "the gem generation" from its naming - Ruby, Sapphire, and Emerald). It was also the first set of Pokémon games to be released on the Game Boy Advance, and it led to large graphical upgrades from the previous games. 135 brand new Pokémon species can be found in Ruby and Sapphire.
Ruby and Sapphire are the first set of mainline games to use a publishing and distribution setup which had The Pokémon Company as the publisher in Japan, Nintendo as the distributor in Japan, and Nintendo as the publisher/distributor in other countries.
Double battles were first introduced in these games, as well as Pokémon Contests, Secret Bases, and Pokémon Abilities. In Ruby and Sapphire and beyond battling environments, e.g. Sandstorm, would inflict damage each turn, and the ground was different. When their sales are combined, Ruby and Sapphire are the best-selling Game Boy Advance games in history. Separately, they are both among the top ten best-sellers for the Game Boy Advance.
- HM06 is now Rock Smash (previously TM08)
- HM07 Dive is added instead of Whirlpool
- HM08 Waterfall has been moved from HM07
In the previous games, you fought the Gym Leaders, beat the Elite Four and your rival/champion. But in Ruby and Sapphire (and Pokémon Emerald) you go back to the hometown, and get given a ticket to go to the Battle Tower/Battle Frontier.
The Bad Guys
Depending on which version you got you faced either:
Pokémon Omega Ruby and Alpha Sapphire
In 2014, the game was remade again in the form of Pokémon Omega Ruby and Alpha Sapphire, which brought new features to the game such as the Fairy-type, Super Training and Pokémon-amie from Pokémon X and Y, new Primal Forms for Groudon and Kyogre, a post-game Delta Episode and all-new characters such as Lisia, Zinnia, and Aarune.
