Look into Nintendo's eshop offerings. The Nintendo published games on the eshop are pretty damn good (Pushmo/Crashmo, Dillon's Rolling Western, Sakura Samurai, Ketzal's Corridors, Freakyforms, etc)

Big fan of RPGs? Get the Denpa Men: They Came By Wave. I don't even like RPGs that much but I enjoyed this dungeon crawler a lot.
