Spec Ops: The Line no doubt. Wasn't necessarily the game I enjoyed the most this year, but when you combine the fact that it had a plot that would shine in any medium, with being a tight video game, with the way it took advantage of the videogame medium to make the player complicit in the action, with the relevance of the story and setting...Then there was also the way it toyed with the expectations set up by the familiar shooter mechanics, and the expectations set up by the "Heart of Darkness" parallels - plenty of games have a "gotcha!" twist, but IMO this game genuinely subverted expectations. Well, all this kind of puts it on a different level than most other games, even most other well-made games.
