@soriku... mmm yeah, plenty of success to go around for the nihon-jin, sure. Let's take a look at the best sellers this and last week...
America:
5. Sonic Chronicles (Sega, DS)
17. Harvest moon Tree of Tranquility (Natsume, Wii)
36. Disgaea DS (Nippon Ichi Software, DS)
Others:
12. Family Trainer (Namco Bandai, Wii)
28. Big Beach Sports (THQ, Wii)
Japan:
10. World Destruction: Michibi Kareshi Ishi DS (Sega)
12. Dragon Ball DS (Namco Bandai)
^*And of course there's plenty more in Japan from japanese developers, but if you look at it the only ones really making money are Namco and Square.
Do I have to make it any clearer for you kid?
