anything from this list http://www.neogaf.com/forum/showthread.php?t=222049
I personally suggest
Professor Layton and the Curios Village - awesome puzzle game, great if you like classic puzzles such as the Tower of Hanoi. It has a few extremely challenging puzzles, but that doesn't stop you from beating the game.
The Legend of Zelda: Phantom Hourglass - if you love Zelda, it is a obvious choice
Advance Wars: Days of Ruin - excellent Strategy RPG, if you like chess or other strategy games, you'll probably like this.
