So I have my Xbox Live account link to 3 different systems. Me & my youngest brother under the same roof & another away at college. Everytime my brother in college try to play a game I've downloaded on my account it tells him he can't play because it's not his game. My account currently isn't under my home but it's home on their xboxs. So is there a way my account can stay home on his system without him having to switch every other day & not waste my limit usage?
