Nintendo reported today that the games combined to sell more than 4 million units across Japan, Europe and The Americas on Saturday, Oct. 12, and Sunday, Oct. 13.

“The early response to Pokémon X and Pokémon Y not only reaffirms the ongoing passion of Pokémon fans, but also indicates that an entirely new generation of gamers is eager to experience the franchise for itself,” said Nintendo President Satoru Iwata.

Since this was the first global launch in franchise history, there isn’t an exact historical precedent for comparison. However, when combining and comparing regional data for previous launches, Pokémon X and Pokémon Y would be the fastest-selling Nintendo 3DS games of all time and are tracking ahead of the last Pokémon RPG titles, Pokémon Black 2 and Pokémon White 2, by more than 70 percent.
