[Rob5VGC]

-Japanese games get bought on Japanese consoles. Nintendo exclusives on Nintendo. Everything else on PlayStation.
-Western games get bought on console with worldwide appeal.
-I go where Tetsuya Nomura wants Kingdom Hearts to go. He wants all the KH games on one console/platform before KH3 releases. The console he chose is PlayStation.
