Hi there, welcome! Omega Ruby, Alpha Sapphire, X, and Y are the newest pokemon games for Gen 6! Omega Ruby is basically like the original Ruby game except with more features like Pokemon Sneaking, Pokedex Habitats, etc, etc. There is a lot to explain, so, you'll be better off asking your questions in some respective threads:
