Well to answer the OP: Because of Zelda Special edition. The first one with the original 3DS and OOT3D. Then I got the XL, because it is just better.
Reasons for newcomers to get the system: Kid Icarus: Uprising, Fire Emblem: Awakening, Pokemon X/Y, Bravely Default, Dillon's Rolling Western and every Atlus game (Etrian Odyssey IV, SMT: Soul Hackers, SMT: Devil Survivor 2 Overclocked).
