Not necessarily unpopular in general, but unpopular within its own series are the DS Zelda games, Phantom Hourglass and Spirit Tracks. These games have some great dungeon design and I really liked most aspects of the touch screen controls (except blowing into the DS). These games used the DS to its fullest and will sadly be locked there as a result. I might have been one of the only people disappointed with Link Between Worlds for adandoning the touch screen for traditional controls.
