For as long as Xbox Live activity has been divulged by Microsoft’s Major Nelson, a first-person shooter has been the most popular title based on the number of unique people playing a game while logged in with the service. Titles from the Gears of War and Halo franchise dot the map in addition to the most recent Call of Duty release at the time which has held the spot for more than two years.

That all changed recently as it was revealed that Minecraft: Xbox 360 Edition is now the most played game on Microsoft’s popular console. The game was first released on Xbox 360 on May 9, 2012 and quickly shot up to second place where it remained under Modern Warfare 3 for several months.

It appears that last week’s 1.8.2 “Adventure Update” was enough to push Minecraft into the top spot, just two weeks before Call of Duty: Black Ops 2 is released. The update introduced Creative Mode, something that Minecraft fans had been looking forward to for quite some time.

Topping Call of Duty is a significant milestone as no other game in the past two years, including the world’s most popular sports franchise FIFA, was able to do so.

The fact that it isn’t a first-person shooter is also significant but even more interesting is the fact that it isn’t a full retail game. Minecraft is sold as a downloadable game from the Xbox Live Arcade and is the first time such a title has been at the top of Live’s activity charts.
