IGN gives Omega Ruby & Alpha Sapphire a 7.8 because of too much water.....

[VXIII]

"Heavily favoring water. It’s especially noticeable in Alpha Sapphire, in which Team Aqua (the villains of the piece) use a lot of water types. It feels like there are water Pokémon in nearly every battle, and I have an overleveled Pikachu to show for it. You also have to navigate many bodies of water"
