5. Cubic Ninja Kingdom Hearts 3D: Dream Drop Distance - The 3D on this game is incredible.
Yes! It's the first game I played mostly in 3D. I actually started to like the feature after this.
My own top-5 would include, in alphabetical order:
Animal Crossing: New Leaf (my favorite Animal Crossing game)
Bravely Default
Kingdom Hearts 3D: Dream Drop Distance (my favorite Kingdom Hearts game)
Fire Emblem: Awakening (my favorite Fire Emblem; yeah I kinda have a trend here)
Rayman 3D (it's a remake of Rayman 2: The Great Escape, which I just love!)
