I want to know if I can change my stats to another account, I was playing on my over account but forgot Ghosts is age rated 17. I was prestige 2 almost 3 and I don't want to do all the work again please help
Why not just play on the account you started on? What does the mature rating have to do with anything?
The problem is my 2nd perstige is my sisters account, I want to use my one and use the username I choose for myself
Unfortunately, I think your options are probably to continue to play on your sister's account, or start over on your own.
