The latest edition in the Pokemon series has sold more than four million units in a single weekend worldwide, Nintendo has said.
Pokemon X and Pokemon Y, which are two slightly different versions of the same game, launched across North America, Japan and many parts of Europe on Saturday.
By late on Sunday, Nintendo claims the games became the fastest selling ever on 3DS (the sales of both were combined).
In what suggests there may still be forward momentum for the series, it was also calculated that X&Y are tracking ahead of Pokémon Black & White 2 by more than 70 per cent.
"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.
In the UK, sales monitor Chart-Track had split the two games into separate entries, meaning that while X&Y came in at third and fourth place respectively, but together they would have outsold the first-placed GTA V.
Nintendo notes that X&Y are the first in the long-running franchise to have a simultaneous launch worldwide, and have performed better than any previously released entries.
"Since this was the first global launch in franchise history there isn't an exact historical precedent for comparison," the corporation said.
"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 per cent."
The title has a long way to go before it becomes the all-time series frontrunner, however. Pokémon Diamond & Pearl, for the Nintendo DS, remains the most popular in the franchise with 17.63 million units sold.
|Pokémon Diamond & Pearl||Nintendo DS||17.63 Million|

In our Pokemon X&Y review we said the games are "a major leap forward for the franchise" and "the first Pokémon game worthy of the 21st century."
