Woolly World is doing very well, as are its wool yoshi's probably.
But I was speaking more of the niche titles that mostly populate the lists. Take LoL, for example, its 31k LTD (NPD) vs. 75k LTD (Japan). That's what I call better than expected considering what the title is, what it was in its major territory, and such.
Similarly, Break Record (enchanced port): 42k LTD (NPD) vs. 75k LTD (Japan).
I believe initial results were with this Miku being the higher selling by a bit (at retail, digital is unknown), but the model for earnings is different so its had to compare.
