Pokémon Omega Ruby (Japanese: ポケットモンスター オメガルビー Pocket Monsters Omega Ruby) and Pokémon Alpha Sapphire (Japanese: ポケットモンスター アルファサファイア Pocket Monsters Alpha Sapphire) are paired Generation VI games that are enhanced remakes of the third-generation titles Pokémon Ruby and Sapphire.
In these remake versions, the main Pokemon Omega Ruby gameplay is almost same as Pokemon Ruby and Sapphire which are published in 2003 with legendaries Groudon & Kyogre. But some points of the story are modified to bring new feelings. You should wait for the release date to know that. There are a lot of new mini missions that make you feel interesting and novelty.
