3DS XL buyers: Today is the last day you can snag a free game with a new 3DS XL. The catch is that you'll have to buy and register either Luigi's Mansion: Dark Moon or Pokemon Mystery Dungeon in order to do so. Once you've registered both your 3DS XL and either game on Club Nintendo, you can choose a free download of Super Mario 3D Land, Professor Layton and the Miracle Mask, Art Academy: Lessons for Everyone!, Star Fox 64 3D, or Freakyforms Deluxe: Your Creations, Alive!
One word of warning if you plan to buy the downloadable versions of either Luigi's Mansion or Pokemon Mystery Dungeon: Be sure to link your 3DS XL to your Club Nintendo account before downloading either game. The deal applies to any 3DS XL purchased on or after February 14, 2013.
