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 title of all time and is tracking ahead of the last Pokémon RPG title, Pokémon Black 2 and Pokémon White 2, by more than 70 percent.
With more than 245 million games sold worldwide, Pokémon continues to be one of the strongest brands in the history of videogames.
