Raptr has begun releasing monthly figures for the most-played Xbox 360 and PC games, and in its first-ever report, Call of Duty: Black Ops II is at the top. Black Ops II came out in November, but the first-person modern combat shooter is still commanding about 7.61 percent of overall gamer time.

Raptr is a gamer social network with 17 million users who share information about their game playing on the Xbox 360 and PC. Since Sony doesn’t allow PlayStation Network members to share game play data, there are no PlayStation 3 games in the rankings. The chart below ranks titles by the percentage of the total time spent on the top 1,000 games played by Raptr users.

While Black Ops II has the lead, it is closely followed by League of Legends on the PC, with 5.9 percent; World of Warcraft for the PC with 3.4 percent, and Gears of War: Judgment for the Xbox 360 at 2.54 percent. Dota 2 (Valve’s battle arena sequel to the Defense of the Ancients mod for Warcraft III) is still in beta but it has climbed up the charts recently, with play time up 63 percent from February. Game time for Dota 2 is half the time of its rival battle arena game League of Legends, but in the last week of March, the gap in playtime was just 25 percent under League of Legends.

Battlefield 3 saw a surge from the release of End Game downloadable content (DLC) in the first half of March. Halo 4 on the Xbox 360, meanwhile, continues a slow decline, with game time down 28 percent compared to February. The largest percentage of those Halo 4 players returned to play Mass Effect 3, thanks to the release on March 5 of the Citadel DLC for that game. A smaller group went to play Gears of War: Judgment.

BioShock Infinite launched on March 26, and the Xbox 360 version was the second-most-played game for that week, with the PC version coming in seventh. Meanwhile, Candy Crush Saga is still the top browser game on Raptr, and Marvel: Avengers Alliance is a distant second, with 25 percent of Candy Crush’s play time.

SimCity had severe launch issues, and it came in 20th for the whole month. During the last week of the month, SimCity was the 34th most-played game.
