Animal Crossing: New Leaf for the sheer amount of things you can actually do in this game. Anyone who buys this game and knows a lick about Animal Crossing will get their money out of it. No questions asked.

Kid Icarus: Uprising

Im going to have to say a tie between Super Mario 3D land and Fire Emblem. I've never played a fire Emblem game before but after playing Awakening I'm a fan of the series. I still go back to play 3D land from time to time, defiantly one of the best game out of the whole 3Ds library.

Wasn't really a fan of Gravity Rush or Golden Abyss but I heard great things about Persona, haven't played it yet though.

Even though it`s just an enhanced version, Monster Hunter 3 Ultimate is an amazing game and the best 3ds game so far, followed closely by Kid Icarus and Fire Emblem.

LBPV

It's by far the best in the series, and all the user made games are amazing too. The arcade games are what really make it shine though.

kid icarus for being new and so well made

Kid Icarus Uprising/Fire Emblem Awakening tie for me

Man I completely forgot about Kid Icarus! Never played it but now I remember people saying it's awesome, I probably would have replaced Zelda with KI in the poll if I had remembered.

KIU!!!!!! FTW!!!!! Edit: i think KIU is winning, most people post it and its not even in the poll lol

Among the games I've played, LittleBigPlanet PS Vita would be the best so far. It's better than LittleBigPlanet 2 which in turn was one of my favourite PS3 games; I think it's quite a feat for a handheld. And the content is going to keep on coming for years.

May have voted for WipEout 2048 if it was in the poll, but I understand why you didn't include it :P
