1. Diablo III: Reaper of Souls
2. Call of Duty: Advanced Warfare
MP continues to be great and bolstered by the new movement mechanics this year. The ways you could customize the appearance of your character was nice.
3. inFamous: Second Son
Looked great and I really enjoyed the different powers and how it changes how you move around the city. Moving around became a genuinely entertaining part of the game instead of a chore like in so many other open world games. In my mind this has always been the biggest strength of the franchise.
4. Bravely Default
Another RPG on this list with a new twist on the classic JRPG battle mechanic.
5. Child of Light
I played it on hard and really enjoyed the battle system. Beating enemies, and especially bosses, on the hard setting required careful use of the slowing mechanic and command options to manipulate battle order. The interruption mechanic is key, and playing on hard made it mandatory to master it instead of it just being tacked on.
The dialog and story weren't great. But the unique battle system alone puts this game on this list.
