There's some pretty good titles too. I got a bunch for cheap (5€~/10€~) that are super fun. Theatrhythm Final Fantasy, Bit Trip Saga, Super Street Fighter and Rhythm Thief. From the eShop I got HarmoKnight, also made by GameFreak.
There's other awesome games, like Monster Hunter, Kid Ikarus, Animal Crossing and Fire Emblem. The online store also has some decent exclusives, and most games have demo for you to try them out.
All in all I was super surprised. The software is not quite good like PS Vita or even PSP, but it's a huge upgrade from regular DS. Also the XL has a beautiful screen and, more important, actually solid buttons. After you use one you won't go back to a regular one.
