We here at Kotaku have been wondering which version of the latest Pokémon game was more popular. X or Y? Whenever we've asked Nintendo, they wouldn't tell us. But perhaps there are other ways to tell?

The challenge is that most of the outfits that talk about Pokémon X and Y's sales combine the two, which takes all the fun out of it.

Nintendo most recently said, in mid-December, that:

Pokémon X and Pokémon Y each sold more than 225,000 combined digital and physical units in their second month on the market. This brought the combined life-to-date total to more than 2.35 million units.


The Japanese game sales tracking service Media Create lists the two as if they were one game. For example, the sales line for 12/30-1/5:

23DSポケットモンスター X/Y(同梱版含む)RPGポケモン1310124,800円

This is no fun. Surely one is more popular than the other. Who can tell us which one?


Thankfully, we've got the UKIE/GfK Chart-Track, the people who track gaming sales in the U.K. and know how to have a good time comparing hit games. Today, they released a list of the 100 most popular boxed games in the U.K. in 2013. Let's look in the mid-20s of that list, shall we?

26. Aliens: Colonial Marines (Sega)
27. Pokémon X (Nintendo)
28. WWE 2K14 (2K Games)
29. Pokémon Y (Nintendo)

Never you mind which quality game outsold Pokémon X. The news here is that Pokémon X trumped Pokémon Y. Or at least the boxed copy did. In the U.K. In 2013. Hey, that's something.


For an equally flawed way to measure this, let's go to the Nintendo eShop:


See that? 24,116 star reviews > 23,549 star reviews. X wins in a squeaker.

Notably, X beats Y while clearly being the inferior game, according to Metacritic—though not according to Metacritic users.


Thus concludes our investigative report on the matter. For now.

UPDATE, 1/17: Nintendo has confirmed that Pokemon X is more popular than Pokemon Y, at least in the U.S. Here are the official U.S. sales figures from Nintendo through the end of December 2013: Pokémon X: 1.63 million, Pokémon Y: 1.54 million.
