In this submitter's opinion, the game of the year for 2012 was Sleeping Dogs. If you were to ask this round's winner, Polarity, to describe why Sleeping Dogs is a great game, he would tell you that it's a game with an excellent story backed up by strong storytelling and excellent martial arts mechanics.
What was once the third instalment in the True Crime series, Sleeping Dogs is like a breath of fresh air in the sea of banality that is the summer of 2012's video gaming line up. Even when that's not considered, Sleeping Dogs is a game that knows exactly what it wants and gives you what it knows you want - a compelling storyline and a host of things to do when you want a break from said story. Perhaps it won't set your world alight as at a cursory glance, the only truly special things about it are the parkour elements and the story, but it's easy to get engrossed in this game and see it as it is, which is a pretty damn good game marred by some ill conceived elements here and there.
