The Legend of Heroes series. How are these games tied together? I know there is *Trails in the Sky* and *Trails in the Sky SC.* Are these completely separate from *Trails of Cold Steel?* Ala Final Fantasy 1 &gt; 2 &gt; 3, etc.

Also, it seems there is (though maybe not ever in the US) a third chapter to *TitS* (Heh.) that is coming out or out in Japan. Is it worth bothering with the first 2 games if the third is never to be?
