This poster's math is where I got the figures from, I thought they were part of the OP at first. I have no idea if his figures are correct but they don't seem unlikely to me at all, considering Golden's opening sales in Japan were 137k.
300k Japan, 400k in the West. Atlus, feed your fans in the scary place across the sea.
Where did that poster even get their P4G numbers? Can't believe it without an actual source.
Regardless, it doesn't matter when the point is that they could gain more western attention, hype and popularity by focusing outside of Japan with things like simultaneous announcements for both audiences such as localization announcements alongside the Japanese ones or an English trailer for a game like PQ posted at the same time as a Japanese one.
I feel that they're getting big enough that they're only doing themselves a disservice by not taking the strategy that other relatively big Japanese devs have with actively showing that they care for the western market as much as the Japanese one in terms of their games.
