On what date did Pokémon X and Y release worldwide simultaneously?

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

The pair were the first Pokémon games to receive a simultaneous global release. They launched on Nintendo 3DS in multiple regions on the same date, a major change from earlier main-series games, which typically arrived in Japan before reaching North America, Europe, and other markets.

X and Y began the sixth generation of the core Pokémon series. They introduced the Kalos region, 72 new Pokémon species, the Fairy type, character customization, and Mega Evolution. They also shifted the main series from sprite-based presentation to fully rendered polygonal 3D graphics.

The simultaneous launch helped create a shared worldwide conversation around the games and reduced the long waits that international players had experienced with earlier releases. The games were announced in January 2013 by Nintendo president Satoru Iwata through a Pokémon Direct presentation.
