NintendoWare Weekly has a classic treat this week with 1988's Zelda 2: The Adventure of Link for $5 on 3DS. If you're looking for something a tad more modern, Crashmo, the sequel to Pushmo is available to help you avoid familial obligations.
There's also the Pokemon-esque augmented reality games Spirit Hunters Inc Light and Shadow for the DSi. More details after the break.
