One of the many reasons why the many Sony zealots out there can't immediately "Dreamcast" the Xbox 360 is because despite the consoles' similarities to each other, the Xbox 360 has one major thing going for it: The Xbox Live Community.

In fact, one could argue that this huge, already existing community, is what's powering the Xbox 360 at the moment, and it's what's giving Microsoft the edge in their drive to get titles for their console.

This partially explains why Xbox Live Activity Charts are worth looking at and worth mentioning. That and it's also handy to know what everyone else is playing. Moreover, you'd be able to know which sub-community of gamers you're going to blame for network slowdowns or what not.

Having said all that, here's the Xbox Live Activity Charts for the week of 1/22 as posted on Major Nelson's:
