It was 340k in October, we are now in the middle of December so its probably closer to 400k. Is not a succes nor a failure, it's still the 2nd best selling game of 3DS out of all the games released worlwide for the system in 2017, so its relatively low numbers are only a sign of how fast 3DS is dying and not a sign of a lack of interest in the franchise. In any case, as great as the game may be, it doesn't seem like the kind of expensive game that needs to reach a milion to be profitable, so once it reaches 500-600k I higly doubt is gonna make them lose any money.
Also... should we really trust VGC numbers when every fucking Switch game is criminally undertracked? Just saying.
