Western = not japanese? And where are the mobile games?
I'm including the USA, Canada, Australia, New Zealand, and every European country as "Western." If anyone wants to argue for including or excluding a country (one could make an argument for Latin America being Western for example), I'm open to suggestions. Note that this does exclude other Asian countries like China and South Korea.
I'm not including mobile games for a few reasons. Part of it is that most of the big mobile games are free with microtransactions, making it hard to compare them to traditional retail games. Another problem is that it's hard to find the actual sales of many mobile games sold in a single country, including Japan. Most of the information I find refers to how much a game grosses or their player counts including those who downloaded a game for free, which is again hard to compare.
Love and tolerate.
