PokГ©mon Emerald is the fifth PokГ©mon game of the advanced generation, after its predecessors FireRed, Ruby and Sapphire. It takes place in the world of Hoenn but acts as a parallel to FireRed and LeafGreen also because of the ability to link with these games as well. Like Pikachu and Suicune were for Yellow and Crystal respectively, Rayquaza plays a vital role in this game along with the other Legendaries, Groudon and Kyogre. Though similar to the original storyline that occurs in Hoenn, Emerald offers a bigger difference than Yellow and Crystal.In terms of gameplay, there have been made several changes to the game.LegendariesAbility to catch Rayquaza before the Elite Four, as well as both Groudon and Kyogre after it.
