"Pokémon has been one of Nintendo's biggest franchises since the original was released in 1996 in Japan for the Game Boy. Pokémon X/Y for the 3DS is the latest game to be released for the franchise. It was released worldwide on October 12.
The game reached nearly 400,000 pre-orders in the US. Day 1 sales have set a 3DS record hitting 5.5 million units. This is also the biggest opening for an exclusive in 2013 and the second biggest opening overall all this year. It was only beaten out by Grand Theft Auto V which sold 17.5 million units in its opening week. However, this was across two platforms."
