@fabinou: Usually people buy less games for handhelds, that they do for home consoles. I don't think piracy has that much to do with it, besides, if it's only about 1st party games, the competition on DS is a lot different, since DS has a shitload of quality 3rd party games.

Nintendo games sell only on Nintendo system.
