I'm Live as well, but all of my time is being spent playing MechAssault. This is totally addictive, and I've already given up being able to have any sort of social life for the next few months. Unreal is a blast as well, and the communication between players is a godsend compared to a keyboard. I'm sure this fact is even more welcome in Ghost Recon, which I won't be playing until after December (read: I'm poor

).
For those interested, my GamerTag is the same as my username here: MoonSka0. I'm always up for playing File members in either MechAssault or Unreal.
