As intelligent as both your arguments are, could we stay on topic?
On the topic of underrated 3DS games, I think Kid Icarus: Uprising was received well, but it still doesn't get the recognition it deserves. The amount of content in the game is amazing and being a first-party Nintendo title, the graphics and music are top-notch. My personal favorite part of the game is the dialogue though, having constant banter during the levels really keeps them interesting and its just plain hilarious sometimes. Seriously, the game has some of the most memorable lines in any video games in years.
But now that i'm done praising it, let me just say: 3DS Game of the Year by far.
