What date marked the worldwide release of Pokémon X and Y?

Pokémon X and Y were released worldwide on October 12, 2013.

The Nintendo 3DS role-playing games were the first main-series Pokémon titles to receive a simultaneous global release. Earlier games had usually reached Japan before North America, Europe, or other markets, so the coordinated launch was a notable change in Nintendo's release strategy.

X and Y introduced the Kalos region, 72 new Pokémon species, the Fairy type, character customization, and Mega Evolution. They were also the first main-series games presented in fully polygonal 3D graphics rather than primarily sprite-based visuals.

The games are paired versions with largely shared stories but version-exclusive Pokémon. Players can trade between X and Y to complete their Pokédex, continuing a tradition that began with the original Red and Green games. Their global launch date is distinct from their January 2013 announcement date.
