I didn't really get a whole lot of new games from 2012. Instead I played a lot of ports and those HD remakes. Tales of Graces f and Virtue's Last Reward are the only things I can think of.
Now that I think about it, Borderlands 2 is the only game I think I've bought this year. While it is certainly a good game, I don't think it's GOTY material.
I think the only games I got were CS: GO and Forza Horizon. I guess forza if I had to choose one, but there is a lot they could've improved on in that game.
Journey, hands down. But then again I don't play many games these days. Too many other obligations. Journey had a strong narrative despite no text; driven by aesthetics, music and contextual storytelling. It is a game I want to foist upon anyone who can appreciate emotional depth.
I found Torchlight II to be great fun for like a month until I burned out, no other game managed that. It isn't an amazing game by any means, but it was very addicting one at that. And solely because after a few minutes of thinking and no other games popping out in my mind, this is my GOTY 2012.
