Here's mine done by Quarters
Q1 Jan-March
Looking I barely played my 3DS, about 20hrs at the max with the most played being Theatrhytham and a few bit's like a hour of paper mario:ss (does TCK no this a RPG right)
Q2 April-June
Looking we had the link between worlds trailer, and quite a few quality games but most played was Fire Emblem Awakening and total time being close to 85 hours.
Q3 July- September
A lot of Animal Crossing New Leaf and a bit of Mario Kart 7 (I'm guessing streetpass events) with a few odd things like Attack of the Friday Monster. Overall Playtime was down to around 40hrs
Q4 October-December
Pokemon and more Pokemon with a bit of Dual Destines & Zelda on the side but my time in total was around the 90hr mark.
