Ghost Trick: Phantom Detective
This game is a puzzle game, made by the creator of Phoenix Wright: Ace Attorney. The game is what you'd expect from Shu Takumi, with crazy characters, ridiculous situations, a captivating story, and a dog named Missile (Kudos if you get the reference). A demo is available on Nintendo Channel
Radiant Historia
If you enjoy RPG's at all, then I highly recomend that you pick up Radiant Historia. The game is very much like Chrono Trigger, but RH has more time period's, a more interesting plot, and one of the most unique battle systems I've ever experienced.
Okamiden
Okamiden is the sequel to the cult hit Okami, where players took on the roll of a god trying to restore the land .Okamiden picks up 9 months later and has the players take on the role of the child of the god who restored land. Defintely worth checking out in more detail via the demo on the Nintendo Channel.
