PC: DayZ Mod (this is also my GOTY out of all platforms not bad for a free game is it lol)
PS3: Walking Dead
Xbox 360: Far Cry 3
Wii U: Only got it today not played a game yet.

Game of the Year: Little Inferno
Honorable Mention: Metal Gear Solid: Snake Eater 3D

My fav games of 2012:

Wii: The Last Story
WiiWare: La-Mulana
WiiVC: Monster World IV

For Wii U it's too early, probably... New Super Mario Bros. U and Little Inferno.

Journey, I played it and I know for certain that this is the peak of my Gaming life. I can quit now Knowing that I have played masterpieces such as these titles and walk away with no regrets.

Honorable mention goes to Kid Icarus, Spent over 90 hours making the perfect weapon and battling buddies. Even if the game is no longer with me, I'm glad to know that a certain kid will experience the same joy I had with it.

Well, this doesn't count but I'm just coming her to say my favorite games this year SO FAR.
Rayman Origins: One of the best platformers of all-time. Awesome gameplay and level design, whismical characters, and beautiful graphics. The game istself is o the level of Donkey Kong Country Returns, which is saying a lot considering it was made by a third-party company.
Donkey Kong Country Returns A Wii essential. It is much better than New Super Mario Wii and one of the best platformers ever. It's better than the SNES games and so creative and greatly made.
Mighty Switch Force It's a great digital game, and a great value. The soundtrack is amazing and tthe theme is very out there. The gameplay is vry creative and the game outdoes its predecessors.

NI NO KUNI

For PS3 killzone and Uncharted
xbox Halo and Gears of wars
Wii U Trine 2 and waiting for monster hunter 3

Etrian Odyssey IV is the only true answer thus far.

Tomb Raider
