I agree that MS should try to entice more japanese developers to port their games to the xbox one. It would make the xbox one's library more diverse and build a better relationship with the japanese in general. That will probably lead to better sales in japan and around the world with future consoles. People other than japanese play japanese games.
It would make a difference on here at the very least. If the majority of the world's gamers have similar opinions on it.....
A site full of Nintendo fans and about half of the Sony fans are going to pick Japanese. If you want the opinions of the world's gamers just look at the sales.
