I can NOT believe that no one mentioned Kid Icarus yet!
Kid Icarus is one of my favorite game of all time, by far my favorite on 3DS (FE is second on the list). Luigi's Mansion is great, but you will not play it nearly as much as KI. I have over 100hours of gameplay on KI and probably around 15hours on Luigi's Mansion. Both are great but KI has wayyyyy more collectibles.
Also Animal Crossing soon if you are into that kind of game, I know I am! hehe
