I don't think anyone can logically argue the 3DS doesn't have games, even with excluding DS titles.
Want some thrills and mystery and exploration? There's Luigi's Mansion, Professor Layton and the Azran Legacy/MiracleMask/vs Phoenix Wright, Zero's Escape: Virtue's Last Reward, etc.
Want an adventure that will eat away more hours of your life than you intended? There's Pokemon XY/ORAS, Pokemon Mystery Dungeon, Monster Hunter 3/4, Persona Q, Shin Megami Tensei IV/Devil Survivor 1&2, Fire Emblem, etc.
Want a life simulator with a twist? There's Animal Crossing: New Leaf, Story of Seasons, Tomodachi Life, Fantasy Life, Nintendogs+cats, Cooking Mama 4/5, Harvest Moon: A New Beginning, etc.
Want an RPG? There's Bravely Default, Conception II, Etrian Odyssey Untold/2 Untold/IV/Mystery Dungeon, Tales of Abyss, etc.
Want something to waste your money on that you'll regret ever purchasing? There's Young Justice: Legacy.
And that's only to name a few. I barley named any 1st party games or download-only titles.
