I have my own gamertag on my brothers xbox 360 and he has his own. Im going to be playing skyrim on my brothers xbox on my own gamertag but ill be playing offline basically the whole time. If im playing offline and then i connect to the internet say a month after playing skyrim. Can i transfer the data that i played on offline to a differnet xbox through my gamertag. sorry its hard to explain but even if im playing offline for a month. then i choose to transfer my data over to another xbox will it save the data i played offline??
