Anfebious on 14 January 2014
I don't have my 3DS with me... But the game where I spent more hours was on Monter hunter 3 Ultimate, Etrian Odyssey 4, Resident Evil Revelations, Shin Megami Tensei 4, Zero Escape Vrtue's Last Reward and... I forgot the rest but those are the ones where I spent more hours.
EDIT: Oh and Pokemon X!
