Dumb thread.
First off Nintendo's first party is not casual. It appeals to everybody which is why they sell so well.
Second, You seem bias towards sony which is strange to see on this site. Japan still sells consoles and games, just not as many. Metal Gear Solid, Final Fantasy, kingdom of Hearts, Monster Hunters, Pokemon anybody?
Third, When any american game reaches Mario or pokemon numbers please let everybody know. The problem with Japanese games is not that they make bad game, it's just that they don't appeal to americans and europeans just like our games dont appeal to them. Besides all of Nintendo's games because as I stated before, they appeal to all ages, all genders, everybody.
