I don't have many games for it, The Legend of Zelda: Ocarina of Time being the only 3D game I have.
But I have some of the 3D apps and a childrens game (for me :3) bought from the Nintendo eShop.
I mostly have it as an upgraded version of the DSLite I had before.
So, I play all my regular DS games on it, like Pokemon Black(1) and White2, and others.
Will be getting the new Mystery Dungeon game for the 3DS, and Pokemon X/Y when they are released.
My code is "3179 - 6546 - 3584"
I shall add you later, as I currently cannot. My bedroom has awful reception for my router's WiFi, so I'll have to take the 3DS elsewhere in the house in the morning.
