Wow, guess I didn't play much games this year to find one I really didn't like XD! 
The 2014 games I got this year were:
-Dont Starve
-Velocity X2
-Bending of Issic Rebirth
-Smash Bros. 3DS
-Sword Art Online: Hallow Fragment
-SteamWorld Dig
-Liftarus (sorry if I miss-spelled that)
-Other Indie games that escape my mind
I also got other games (recently KH3D and a number of PSP/PS1 games on PSN), but they don't count. 
If I had to pick one I liked the least....I guess Don't Starve? I mean, I love its art design, the open world it has and how threatening things can get if you are not careful. But, I only played it maybe twice and never went back to it 

. So....I guess that counts for this? I don't hate the game (far from it; it was enjoyable the little time I put into it 

) but I bearly played it....so maybe it didn't 'click' with me :l.
It really sucks so many big AAA games are falling flat on their face this year X(; Destiny, Watch Dogs, MCC, and many more just not working day one or disappointing everyone 

. 
Maybe next year will be better for next-gen gaming 

. Also, Nintendo killed it this year 

! Smash, Mario Kart 8, DKC: Tropical Freeze, and Hyrule Warriors really pushed the system into must-own status for many gamers (hell, it was the reason I got my 2DS; had to play Smash Bros. somehow XD!).
