Important Importables: DS games the US won't get

From the article, "It's a given that not all Japanese games will make it outside of Japan. Some didn't sell well enough in that country, others were too focused on a certain age group and sometimes they're just too weird.

At the same time, there are quite a few phenomenal or funny games which should get a worldwide release, but don't. Sadly, gamers don't get a list of reasons from publishers or developers as to why we'll never have the honor of playing a domestic version of one of these titles, but usually it is pretty easy to understand why."
