GOTY 2013
Honourable Mentions:
Animal Crossing: New Leaf - I got really addicted for a while, it's totally animal crossing though.
Phoenix Wright Ace Attorney: Dual Destinies - They made another phoenix wright game.
Bravely Default - Haven't played enough to judge it really. Seems fantastic though.
Assassins Creed 4: Black Flag - Have only played a few hours but seems like a return to form for the series.
