I thought Japan was irrelevant?
Someone also told me that UK was the biggest after US?
Did NewGAF lie to me?
No, but that was a few years ago when Japan fell out of love with console gaming post PS3 launch and mobile gaming wasn't the behemoth it is today.
UK was a massive market for 360 and PS3 (Edit: And Wii of course!) and while the PS4 and Xbox One sell well here It's noticeably dropped since the heights pre 2009.
