they just don't like the one genre western markets can't get enough of . And actually with 100k 200k success in those genres , they are more open that the western markets . Even not going by percentage and only with pure numbers : vanquish , bayonetta, rhythm heaven , eba , sinandpunishment 2, el shaddai all sold less in western markets than cod or gta did in japan . And really keeping in mind that the one million threshold was only crossed once for the ps3 , well 10% of that is quite a lot . Japanese games should reach 300k 400k comparatively to total sales in order to be the equivalent of the western games in japan.
