Statically speaking, that’s about 150 achievements per Xbox Live member. As of now, the collective Gamerscore went up to an impressive 52 billion points

Apparently, the Achievement grew into something much larger than Microsoft expected and are now driving sales up to new heights. Or, at least, that’s what the Redmond company seems to think:

"We never anticipated this reaction… where there are achievement fan sites and people playing games that they would never play [for the achievement points]," says Aaron Greenberg, director of product management for Microsoft’s Xbox division

Microsoft might have some impressive numbers on its hands, but its doubtful that Achievements are actually a significant boost for sales. It may lure gamers as a bonus, but it’s more likely that it makes the difference between one Xbox 360 game and another.

In the end, we were inclined to comment that more game Achievements means less real life Achievements, but we chose to say nothing about it.
