All of Nintendo's games work?
I'm sorry, but since when are Zelda and Metroid popular in Japan? :P
Nintendo's most popular games - Mario Kart, Wii Sports, Wii Fit, and Mario games sell great in the west and the east because they aren't western, and they aren't Japanese, they are Global, they don't have characters, they don't have narrative, they exist in their own world, and they work.
Bet with Dr.A.Peter.Nintendo that Super Mario Galaxy 2 won't sell 15 million copies up to six months after it's release, the winner will get Avatar control for a week and signature control for a month.
