I think the problem is that japanese gaming market just rejects western games, even the ones they would like, Winning Eleven sells well in Japan because it's made by a japanese company, but Fifa sells poorly, if you like winning eleven probably you would like Fifa too... Like Gta, it received a really high grade from Famitsu but probably won't reach a million, western market don't reject the well done japanese games(sometimes they sell more than in Japan), but japan reject well done western games, why?
