there will be an update for the xbox in the fall where you can create your own avatars and stuff
it's gonna be free most likely
and i dunno if you have to have live to get it
they said on G4 that if you didn't have live they'll ship the update on a memory thing probably to your house or sumthing like that
but they said that microsoft wanted all the people with an xbox360 to have this update
it's supposed to change gaming forever and you can have live chats with your avatars and everything with lots of customization on your avatar
