It was a down year for AAA games (which is why its the only year an indie game was the consensus game of the year). But it was a great year for indie, mobile, handheld, and generally smaller games.
I like all kinds of niche shit (see my ballot this year) and so do a lot of people I like, and the way I remember it everyone seemed to agree 2012 was a big miss. Some solid games of course, even 1 of my GOTG's (Tokyo Jungle), but as a whole, very little to get excited about.
