VGA 2012 is around the corner, so it would be interesting to see what VGChartz community thinks is the game of the year.

EDIT: To make things bit more clear (if not obvious from the start) - these are OFFICIAL VGA nominees, as selected by VGA Advisory Council:

General public can only vote in 2 categories at:

and we can "pick" the rest at:

Good debate on nominees (Invisible Walls on GT):

Rayman Origins.

From your list though dishonored.

For me? It was probably AC3. I like how big it is and I enjoy some of the added RPGish elements aswell as how the different parts tie together. Not perfect of course, but better than anything else that came out this year.

Now that I think of it there haven't been a ton of great games this year.

Oh man! I forgot about Journey...I'd have to say...Journey was better than AC3 but maybe just too short to win GOY? Just maybe though.

Where is Borderlands 2???

Sorry, just official VGA nominees as choice...

New Super Mario Bros U. Oh, wait, these are the VGAs, so no Nintendo games.

Halo 4 then. Wait, what!?

Seriously, from that list... Dishonored.

Well, these folks choose games (great IW on GT btw, they had a lenghty discusion about all nominees):

Halo 4.

But considering that it's the lolVGA's:

Mass Effect 3 -> Dishonored -> Rest ----------------------> AC3

The Walking Dead was so close to being one of the best games this generation let alone this year. Then I noticed your choices don't mean anything.
