In terms of sales and success, i would say Splatoon. I was one of those who have underestimated it since the game looks very "Cheap" and a New IP on a console which is not doing soooo great. I knew that i was gonna love it (even though the shooting genre isn't my cup of tea).
In terms of gameplay and the other content in the game i would say Fire Emblem Awakening. I remember getting hooked to it by just watching this trailer which shows the different classes (I just love when theres soooo many options you can do in a game). I havent played any game which uses that similar gameplay, sooo my expectations were quite not high on it.
I would also say Mario Kart 8. When i went to each track for the first time i just shout "WOOOOOOOW" The quality from Nintendo has never looked so good.
Pocky Lover Boy!
