In the order they were bought or received:

1. The Legend of Zelda: Ocarina of Time 3D-I waited for this game to release before getting my 3DS. Wish I'd done the same with my Wii U and Wind Waker.
2. Starfox 64 3D
3. Super Mario 3D Land
4. Mario Kart 7
5. Super Street Fighter IV 3D
6. Kid Icarus: Uprising *
7. Mario Tennis Open
8. Kingdom Hearts 3D: Dream Drop Distance *
9. New Super Mario Bros. 2
10. Rhythm Thief and the Emperor's Treasure *
11. Paper Mario: Sticker Star
12. Professor Layton and the Miracle Mask *
13. Art Academy: Lessons for Everyone *
14. Fire Emblem: Awakening *
15. Brain Age: Concentration Training *
16. Luigi's Mansion: Dark Moon *
17. Donkey Kong Country Returns 3D
18. Animal Crossing: New Leaf *
19. Mario & Luigi: Dream Team *

And soon to be up to 23 games at the end of this year as I'm getting Pokemon X, Pokemon Y, The Legend of Zelda: A Link Between Worlds, and Mario Party: Island Tour (as a gift). It should also be noted that my 3DS library has BY FAR the highest completion rate of any previous handheld or console I've ever owned. I've beaten EVERY 3DS game I own except for Luigi's Mansion and Mario & Luigi (currently playing). I LOVE 3DS!

One last note: a * means it's the first time I've owned/played a game in that franchise. My 3DS library is also far more diverse than any other console/handheld library I've owned...especially considering I'm only a little over 2 years in.

I feel terrible...I have a decent list but it's NOT as good as some other people's. then again, I also have a list of like 30 Vita titles, so my handheld awesomeness has been more evenly dispersed. Can't have it all, you know?
