This looked like a very lackluster year to me. Smash for WiiU was ok but ultimate makes it redundant.
Other Divinity: Original Sin get my vote.
In fairness I should make room for that game and/or the second installment in my top 50. The strategic battles and freedom of solving problems in many different ways set this apart from other RPGs at the time. But it was the excellent multiplayer that won me over. Played it with my at the time long distance girlfriend and had a blast. We sank over 100 hours into it.
