I'm being a little more lenient here so here goes :
Fire Emblem Awakening - it's my favorite 3DS game and I couldn't really find anything at all wrong with the game. It has good graphics, challenging gameplay, lots of characters to play with and the humor is there.
Super Smash Bros. for 3DS - surprisingly, Smash Bros. isn't bad on the small screen. Although it lacks a story mode (which I'm not sure about how it works since this is my first Smash game), it keeps you entertained with Smash Run, Vs and Classic modes. It also has really good online features which I commend the developers for,
Shin Megami Tensei: Devil Survivor Overclocked - Good storyline, interesting characters and challenging gameplay. I just wished there were more demons in the game but it's enough to satisfy my needs,
The Circe Pad might not make the game a perfect 10, but hey, I did say I'm being lenient, didn't I?
Virtue's Last Reward - One of the best visual novels and puzzle games that I've played on the Nintendo 3DS.
Animal Crossing: New Leaf - The game is designed to keep you playing for a long period of time. It is addictive because I've actually lost track of the time while playing when I first picked this game up. Even without multiplayer, the game is solid imo.
