Is there a difference between Pokemon Ruby X version and Pokemon Ruby Y version?

The difference between x and y lies in the way to get some PM. The following wizards can only be captured in the X(Y) version:

The pets restricted by version X are: Staryu, Starmie, Dajia, Darubi, Heluga, German Shepherd, Mightyena, Cocodora, Cordola, Bosco Dora, Ghostbusters, Leprechauns and their evolution.

デッポァ and its evolution ブロスター (lobster), the goblin is the god beast ゼルネネスス (that is, God X)

The pets limited by the Y version are: big tongue shell, armored shell, Heraclos, Uchila, Shakira, Bangila, Juan Carlos, lightning beast, pickpocket cat, cool leopard, projectionist, demon spirit and their evolution.

In addition, the megalith version needed for megalith evolution is limited. Version X is limited to: Fire-breathing Dragon Stone X, Super Dream Stone X, Heraclos Stone, Bangila Stone and Lightning Beast Stone. Version Y: Fire-breathing Dragon Stone Y, Super Dream Stone Y, Dajia Stone, Bosco Doraemon Stone, Heluga Stone.

So you can choose the version according to your preference for some PM. In addition, if you can connect online, if your online partner chooses a certain version, then you can choose another version to collect pictures through the exchange of exclusive pets.

(Correcting the upstairs view, God X and God Y have the same racial value, and God X has a proprietary strengthening technique, which has greater attack power and is superior to God Y in strength. )
