What was the first Pokémon main-series release to launch worldwide on the same day?

Pokémon X and Y were the first Pokémon main-series games released worldwide on the same day.

The sixth-generation games launched on October 12, 2013, for Nintendo 3DS. Earlier main-series Pokémon games typically reached Japan first and arrived in North America, Europe, and other regions months or years later. A simultaneous release changed how fans around the world experienced a new generation.

The games’ global launch also helped limit spoilers and made international online discussion more synchronized. Players everywhere began exploring the Kalos region, collecting the new species, and discovering the Fairy type at nearly the same time.

Pokémon X and Y were also notable for fully 3D polygonal graphics, character customization, Mega Evolution, and the first appearance of the Kalos region. Their paired titles feature different legendary Pokémon and version-exclusive creatures, preserving the series’ long-running emphasis on trading between editions.
