Xbox Live: 2,500,000,000 Achievements Unlocked

Xbox 360, PC, Wii, doesn't matter, everybody loves online user statistics. Especially when, they get into the billions, as was revealed by Microsoft's Aaron Greenberg last week.

Contributing to a Gamasutra piece on achievements, Greenberg revealed that, as of this month, there have been 2.5 billion achievements unlocked by the Xbox Live user base.

They all add up to a whopping 52 billion gamerscore points. Or, if you break that down across the install base, around 150 achievements per user.
