Diablo III just won by a landslide. Google Zeitgeist posted the most-searched-for terms of the year across the world, and Blizzard's action-RPG clicked in at number five. While it wasn't enough to topple Gangnam Style, it was by far the highest game mentioned in the overall list.
Diablo III also topped the video game list in the United States, beating out other major titles like Mass Effect 3 and Halo 4.
According to Google, the lists were "ranked in order of the queries with the largest volume of searches."
